AOS-SOR358464H - a Rockchip RK3588 Android and Linux OPS module with an integrated 6 TOPS NPU, one of the four AIOSTAR slot-in platforms mapped to deployment environments in this guide.

Slot-in OPS compute is a fit decision before it is a specification. Four projects can all be described as an OPS PC job and still need different hardware: a classroom interactive whiteboard that runs teaching software and touch applications every school day, a meeting room that alternates between video conferencing and whiteboarding, a commercial display that plays a scheduled loop and receives remote content updates, and an LED video wall that renders continuous high-resolution graphics. The module has to match the environment, the duty cycle and the control behaviour the integrator needs - not only the processor name.

For AIOSTAR's slot-in range, the environment-to-module mapping is:

• Classroom interactive whiteboards and teaching displays - AOS-SOHAUF41SC, an Intel Alder Lake-U OPS-C module.
• Meeting rooms and collaboration displays - AOS-SOZK6A341SXGE, a Zhaoxin KX-6780 series domestic-platform OPS-C PC.
• Digital signage and smart retail - AOS-SOR358464H, a Rockchip RK3588 Android and Linux OPS module with a 6 TOPS NPU.
• LED video walls and visualization projects - AOS-SOH61I41SXG, an Intel H610 OPS PC with optional discrete graphics.

AIOSTAR is the brand of Shenzhen Aiostar Electronics Co., Ltd., a computer hardware supplier established in 2015 in Shenzhen, China, which develops, produces and supplies OPS PCs, OPS-C pluggable computer modules, Android OPS PCs, industrial motherboards, mini PCs, BOX PCs, industrial panel PCs, servers and customized embedded computer systems. Its products are used in interactive displays, digital signage, education, corporate meetings, industrial automation, smart transportation, retail and security projects, and its OEM and ODM services cover hardware configuration, I/O, chassis, cooling, BIOS, operating system image, logo, packaging and accessories.

This guide explains what each of the four deployment environments demands, how slot-in installation and control behaviour should be specified, and what has to be verified before a module is released to mass production.

Why slot-in compute projects fail on fit, not on processing power

Most failed OPS deployments are not processor failures. They are fit failures, and they usually surface in five places.

Slot standard mismatch. Intel's Open Pluggable Specification (OPS) standardises the mechanical and electrical interface between a display and a media player around a unified 80-pin JAE connector with a footprint of 180 mm x 119 mm x 30 mm. OPS-C is a separate variant widely adopted in the Chinese domestic market for educational interactive whiteboards, and its mechanical envelope differs; industry consensus figures commonly cite approximately 180.8 mm x 195.2 mm x 42.5 mm. A module built for one standard does not simply drop into the other.

Duty cycle and thermal headroom. A classroom module that supports interactive lessons five days a week and a signage module that plays continuously for months sit on different thermal plans, even when both are described as indoor use. Cooling design, power adapter selection and airflow inside the display cavity all follow from the duty cycle, and the corpus treats heat dissipation as a named confirmation item for large-format visualization projects.

Control behaviour assumptions. Integrators often assume remote power-on, scheduled wake-up or automatic recovery after a power interruption is included by default. Wake-on-LAN, auto power-on and watchdog functions are BIOS-level behaviours that belong in the configuration discussion - on the AOS-SOHAUF41SC they are explicitly listed as available by BIOS configuration, and on other platforms the equivalent behaviour has to be confirmed against the selected BIOS and project setup rather than assumed.

Display and peripheral compatibility. Touch modules, cameras, microphone arrays, conferencing clients and content management systems sit outside the module but inside the project. AIOSTAR's scenario profiles treat this as a compatibility checklist rather than an afterthought: camera, microphone, touch, display output, operating system and conferencing software compatibility for meeting rooms; codec, resolution, content management software, storage, network and thermal requirements for signage.

Serviceability over the deployment life. The module is the part most likely to be upgraded or replaced, and a removable slot-in format keeps that decision independent of the display. AIOSTAR's OPS-C module is compatible with mainstream OPS-C specifications, and the removable slot-in design simplifies installation and maintenance.

All four of AIOSTAR's display scenario profiles end with the same instruction in different words: verify against the target display before production. That single discipline removes most of the risk described above.

Industry background: slot-in compute inside a large display market

The global Interactive Flat Panel (IFP) market, the primary application for OPS PC modules, was valued at approximately USD 12.6 billion in 2024, according to a market research report published by Grand View Research. The broader industrial PC market, which includes industrial-grade OPS modules, was estimated at USD 6.48 billion in 2024 and is projected to grow at a compound annual growth rate of 6.30% through 2032, per Grand View Research. Estimates vary between research houses - Precedence Research places the 2024 industrial PC market at USD 5.36 billion - largely because of different boundaries between embedded and standalone systems, so these figures are best read as scale indicators rather than precise totals.

Inside interactive flat panels, integrated OPS-slot compute modules and Android-based SoC modules are estimated to ship in 15-25% of new IFPD units, based on a 2023 IFPD market trends report. A separate AV supplier industry guide projects the global interactive whiteboard market to reach USD 730 million by 2030 and describes OPS penetration as a key growth driver for modular classrooms.

For project teams, the practical reading of this data is standardisation rather than market size. Because slot-in compute is a defined interface, the compute can be specified, tested and swapped independently of the display. That is what makes environment matching possible in the first place - and it is why the same display model can go into a classroom, a boardroom or a retail lobby with a different module behind the panel.

Matching the module to the deployment environment

Classroom interactive whiteboards and teaching displays

Classroom deployments are the most demanding on interaction rather than graphics. The AIOSTAR education technology profile describes an indoor classroom with daily operation, touch interaction and networked teaching applications, running teaching software, touch applications, media playback and video conferencing, with supporting equipment that includes an interactive flat panel, a touch module, camera, microphone, speakers and LAN or Wi-Fi connectivity.

The module listed for this environment is the AOS-SOHAUF41SC, an Intel Alder Lake-U OPS-C PC. CPU options include Intel Core i5-1235U and i5-1240P; memory is configurable SO-DIMM and storage is a configurable M.2 SSD; Windows or Linux is selected by configuration; and the unit installs in an OPS-C slot. Wake-on-LAN, auto power-on and watchdog functions are available by BIOS configuration - the three control behaviours that matter most when a school needs to power a room remotely or recover a display without sending a technician.

The pre-production checklist for this environment is explicit: verify mechanical size, connector pinout, display resolution, cooling and operating system image before mass production.

Meeting rooms and collaboration displays

The meeting room profile is defined by multi-user touch and video conferencing under scheduled and on-demand use. The module provides the computing platform for conferencing, document sharing, whiteboarding and presentation, operates in slot-in installation mode with local operation and network access, and supports optional auto power-on. Supporting equipment typically includes the interactive display, camera, microphone array, speakers, touch controller and network.

For this environment the corpus maps the AOS-SOZK6A341SXGE, a Zhaoxin KX-6780 series OPS-C PC. The platform supports Zhaoxin KX-U6780A, KX-U6740A, KX-U6640A and KX-U6640MA processors, provides six USB ports including two USB 3.0 ports, and offers optional GT730, GT1030, GTX 1050 or GTX 1050 Ti graphics depending on configuration. Memory, storage, operating system and project I/O are configurable, and the unit installs in an OPS-C slot. Its stated scope covers domestic-platform interactive displays, education, government information systems and project-specific commercial displays - relevant where a domestic CPU platform is a project requirement rather than a preference.

Compatibility confirmation here is wider than the display itself: camera, microphone, touch, display output, operating system and conferencing software all need to be confirmed before the configuration is frozen.

Digital signage and smart retail displays

Signage moves the requirement from interaction to endurance and remote management. The AIOSTAR digital signage and smart retail profile describes an indoor commercial environment with scheduled or continuous media playback and remote content updates. The module decodes and displays scheduled video, images and information content, and operates with local or network-based content management. Supporting equipment includes the LCD or LED display, content management system, network connection, speakers and optional sensors.

The mapped module is the AOS-SOR358464H, a Rockchip RK3588 Android and Linux OPS module. It uses an octa-core CPU up to 2.4 GHz with an integrated 6 TOPS NPU; standard memory is 4 GB LPDDR4 with up to 16 GB optional; storage is eMMC; and Android 13, Ubuntu or Debian can be selected. The specification notes that 8K multimedia capability depends on firmware and interface configuration - a useful reminder that signage playback performance is a firmware, codec and interface question, not only a silicon question. The integrated NPU also places this module in edge-AI display terminals, where on-device inference for smart retail or information kiosks is part of the brief.

Confirmation items for this environment are codec, resolution, content management software, storage, network and thermal requirements.

LED video walls and visualization projects

LED walls and visualization work runs continuously indoors under the large-format visualization profile: high-resolution graphics, optional multi-display output and extended operation in an indoor controlled environment. The module is installed in the display's OPS slot and runs continuously or on a defined schedule, providing high-resolution content playback and optional GPU-assisted workloads.

The module matched to this environment is the AOS-SOH61I41SXG, an Intel H610 OPS PC with optional discrete graphics. It supports selected 12th and 13th Generation Intel Core i3, i5 and i7 processors and provides HDMI, HDMI and DisplayPort video outputs, with up to 8K 60 Hz output subject to the selected CPU, GPU and display configuration. Optional discrete graphics are available by project. The unit installs in the display's OPS slot using a slot-in OPS format, with configurable memory, storage, video outputs, cooling and operating system.

This is the environment where pre-confirmation matters most. The corpus requires confirming GPU model, power budget, heat dissipation, output resolution and display compatibility, with supporting equipment that includes the large-format display, LED controller or video wall controller, content system and network.

Step-by-step: specifying and validating a slot-in OPS PC

The sequence below follows the order in which design decisions lock, so that mechanical, thermal and software constraints are settled before configuration is committed.

Step 1 - Define the environment and duty cycle

Write down where the module will live and how long it will run: daily touch interaction and networked teaching in a classroom; scheduled and on-demand use with multi-user touch in a meeting room; scheduled or continuous playback with remote updates in signage; continuous operation in an indoor controlled environment for LED walls and visualization. Duty cycle drives the cooling, power and storage conversation.

Step 2 - Select the compute platform

Platform follows the software stack. Intel Core options (AOS-SOHAUF41SC with Core i5-1235U or i5-1240P; AOS-SOH61I41SXG on the Intel H610 platform with selected 12th and 13th Generation Core i3, i5 and i7) suit Windows or Linux teaching and conferencing software and multi-display graphics. The Rockchip RK3588 module (AOS-SOR358464H) suits Android or Linux content pipelines and edge-AI display terminals. The Zhaoxin KX-6780 platform (AOS-SOZK6A341SXGE) suits projects that specify a domestic CPU platform.

Step 3 - Lock the mechanical and electrical interface

Confirm whether the display expects Intel OPS (80-pin JAE, 180 mm x 119 mm x 30 mm) or OPS-C, whose envelope differs, and verify connector pinout against the display vendor's documentation. The AOS-SOHAUF41SC and the AOS-SOZK6A341SXGE both install in an OPS-C slot; the AOS-SOH61I41SXG uses slot-in OPS installation. For classroom projects the verification list is mechanical size, connector pinout, display resolution, cooling and operating system image - completed before mass production, not after.

Step 4 - Specify control and power behaviour

Decide whether the module will be operated locally, over the customer's network, or both. Wake-on-LAN, auto power-on and watchdog functions are listed as available by BIOS configuration on the AOS-SOHAUF41SC; meeting-room projects list optional auto power-on as part of the operating mode; signage projects specify local or network-based content management. Where remote wake or auto-recovery is a project requirement, it should be confirmed against the selected BIOS and platform during configuration.

Step 5 - Match video output to the display

For LED walls and visualization, confirm output resolution, GPU model, power budget and heat dissipation together, because up to 8K 60 Hz output on the AOS-SOH61I41SXG is subject to the selected CPU, GPU and display configuration, and optional discrete graphics are project-specific. For meeting rooms, confirm display output alongside camera and touch behaviour. For signage, confirm codec and resolution alongside the content management system.

Step 6 - Validate software, peripherals and content pipeline

Confirm the operating system image and the software stack: teaching software and video conferencing in classrooms; conferencing clients, whiteboarding and document sharing in meeting rooms; codec support, storage sizing and network reach in signage; content system and controller compatibility in visualization. Peripheral confirmation covers touch module, camera, microphone array and speakers where they apply.

Step 7 - Run a pre-confirmation test on the target display, then scale

The decisive test happens on the customer's own display, not on a bench. Only after the module passes that stage should production quantities be planned. AIOSTAR supports this with configurable builds (CPU platform, memory, storage, I/O, chassis size, cooling solution, BIOS functions, operating system image, logo, packaging, power adapter and cables), a monthly capacity of more than 5,000 units and a standard lead time of 60 days.

Quality documentation and testing records support the pre-confirmation stage of an OPS PC project before mass production is released.

Use cases in practice

Classroom rollout. A teaching display schedule of six hours a day, five days a week, with interactive whiteboard software and networked lesson content, is served by the AOS-SOHAUF41SC: OPS-C slot-in, configurable SO-DIMM memory and M.2 SSD, Intel Core i5-1235U or i5-1240P options, and BIOS-configurable Wake-on-LAN, auto power-on and watchdog functions for remote room management.

Meeting room standardisation. Where a customer wants one module type across a building's collaboration rooms, the AOS-SOZK6A341SXGE provides a domestic-platform OPS-C PC with six USB ports, two of them USB 3.0, optional GT730, GT1030, GTX 1050 or GTX 1050 Ti graphics, and configurable memory, storage and project I/O. Camera, microphone, touch, display output, operating system and conferencing software compatibility are confirmed per room standard.

Signage network. A retail or lobby network that pushes scheduled content and updates remotely is served by the AOS-SOR358464H, an Android and Linux OPS module with Android 13, Ubuntu or Debian options, eMMC storage, 4 GB LPDDR4 standard memory with up to 16 GB optional, and an integrated 6 TOPS NPU for on-device inference.

LED wall and visualization. Continuous high-resolution playback with optional GPU-assisted workloads is served by the AOS-SOH61I41SXG, with HDMI, HDMI and DisplayPort outputs and up to 8K 60 Hz output subject to the selected CPU, GPU and display configuration.

Reference deployment. AIOSTAR supplied 1,000 units of the AOS-SOZK6A341SXGE for an OPS adapter board application to an industrial or transportation solution provider in Japan. The case record lists a deployment duration of three to seven years with stable operation results, and highlights compatibility with mainstream OPS-C specifications, a removable slot-in design that simplifies installation and maintenance, and configurable memory, storage, BIOS and operating system images to support different interactive-display projects.

Frequently asked questions

Do OPS and OPS-C modules follow the same mechanical standard, and what must be verified for compliance?

No. Intel's Open Pluggable Specification defines a unified 80-pin JAE connector and a footprint of 180 mm x 119 mm x 30 mm, while OPS-C is a separate variant widely adopted in the Chinese domestic market for educational interactive whiteboards, with an envelope that differs; industry consensus figures commonly cite approximately 180.8 mm x 195.2 mm x 42.5 mm. Because the two are not interchangeable by default, compliance for a specific project is confirmed by verifying mechanical size, connector pinout, display resolution, cooling and operating system image against the target display before mass production - the same verification list AIOSTAR applies to education-technology projects. Serviceability matters alongside dimensions: AIOSTAR's OPS-C module is compatible with mainstream OPS-C specifications, and the removable slot-in design allows the module to be exchanged without replacing the display.

How do I choose between an Intel OPS PC, an Android RK3588 module and a Zhaoxin KX-6780 platform?

The choice follows the software stack and the project's platform requirements rather than a performance ranking. Intel platforms suit Windows or Linux teaching and conferencing software and multi-display graphics: the AOS-SOHAUF41SC offers Intel Core i5-1235U and i5-1240P options in an OPS-C slot, while the AOS-SOH61I41SXG runs on the Intel H610 platform with selected 12th and 13th Generation Intel Core i3, i5 and i7 processors, HDMI, HDMI and DisplayPort outputs and up to 8K 60 Hz output subject to the selected CPU, GPU and display configuration. The AOS-SOR358464H uses a Rockchip RK3588 octa-core CPU up to 2.4 GHz with an integrated 6 TOPS NPU and Android 13, Ubuntu or Debian options, which fits Android content pipelines and edge-AI display terminals; its 8K multimedia capability depends on firmware and interface configuration. The AOS-SOZK6A341SXGE supports Zhaoxin KX-U6780A, KX-U6740A, KX-U6640A or KX-U6640MA processors with optional GT730, GT1030, GTX 1050 or GTX 1050 Ti graphics, for domestic-platform interactive displays, education, government information systems and project-specific commercial displays.

What drives the cost and MOQ of a custom OPS PC module?

Configuration drives cost, not the product name. AIOSTAR's customization scope covers CPU platform, memory, storage, I/O, chassis size, cooling solution, BIOS functions, operating system image, logo, packaging, power adapter and cables, and each of those decisions changes the build. Graphics is a common variable: the AOS-SOZK6A341SXGE offers optional GT730, GT1030, GTX 1050 or GTX 1050 Ti graphics depending on configuration, and the AOS-SOH61I41SXG makes optional discrete graphics available by project. For evaluation, MOQ is 1 unit for samples; the MOQ for a customized production project depends on the configuration agreed. Buyers comparing two OPS PC quotations should therefore compare the configuration list first and the price second.

How does sample evaluation and pre-confirmation testing work?

Evaluation starts with a sample, since MOQ is 1 unit for evaluation samples. Because the module sits inside someone else's display, the decisive test is not on a bench but on the customer's target display. Before mass production, AIOSTAR's project requirements specify verifying mechanical size, connector pinout, display resolution, cooling and operating system image; for meeting-room projects the list extends to camera, microphone, touch, display output, operating system and conferencing software compatibility, and for LED wall or visualization projects to GPU model, power budget, heat dissipation, output resolution and display compatibility. Quality control covers incoming material inspection and functional and interface testing of finished units, with burn-in testing when specified and temperature, humidity, vibration and drop testing arranged according to project requirements.

What lead time, capacity and support can a project expect?

Standard lead time is 60 days with a monthly capacity of more than 5,000 units, which is enough headroom for staged rollouts such as the 1,000-unit OPS adapter board deployment AIOSTAR supplied in Japan to an industrial or transportation solution provider, where the recorded result is stable operation. After-sales support includes remote technical support and BIOS, operating system and driver assistance, with a one-year warranty unless otherwise agreed in the quotation or proforma invoice. Project teams that want to check a configuration before committing can review the introduction brochure or send the display model, module requirement and target quantity to salesos@aiostar.com for a fit check.

Conclusion: match the module to the environment, then verify on the display

Slot-in compute succeeds when the module is chosen for the environment rather than for the specification sheet alone. Classrooms need daily touch interaction and networked teaching, served by the AOS-SOHAUF41SC with BIOS-configurable Wake-on-LAN, auto power-on and watchdog functions. Meeting rooms need multi-user touch and video conferencing, served by the AOS-SOZK6A341SXGE with six USB ports and optional discrete graphics. Signage needs scheduled or continuous playback with remote updates, served by the AOS-SOR358464H with Android 13, Ubuntu or Debian options and a 6 TOPS NPU. LED walls and visualization need continuous high-resolution output, served by the AOS-SOH61I41SXG with HDMI, HDMI and DisplayPort outputs and up to 8K 60 Hz output subject to the selected CPU, GPU and display configuration.

Whatever the environment, the last step is the same: verify mechanical size, connector pinout, display resolution, cooling and operating system image on the customer's target display before mass production. That is the step that converts a module specification into a project that runs.

Evaluation samples are available at MOQ 1 unit so integrators can test a module on the target display before committing to production.
