What to Include in an OEM Motherboard Project Specification

An OEM motherboard project begins with a well-defined technical specification. Before choosing a processor or designing the PCB, manufacturers must understand the product’s intended application, performance needs, interfaces, operating system, and production goals.

A thorough specification can minimize design revisions, reduce development time, and help ensure that the finished motherboard satisfies the end product’s requirements.

1. Product Application and Project Requirements

First, define where and how the motherboard will be used.

Key details include:

• Target application: industrial control, robotics, smart home, digital signage, medical terminals, or IoT devices.
• Operating environment: indoor, outdoor, industrial, or embedded installation.
• Expected operating hours and service life.
• Installation method and available space.
• Required certifications and industry standards.

The intended application guides the hardware architecture and environmental requirements.

2. Processor and Computing Performance

Selecting the processor is one of the most critical decisions in motherboard design.

Specify:

• Processor platform: Rockchip, NVIDIA, MediaTek, Intel, AMD, or another platform.
• CPU architecture and number of cores.
• Required GPU performance.
• AI computing needs, including NPU performance in TOPS, where applicable.
• Video decoding and encoding capabilities.
• Memory and storage capacity.

For example, Rockchip platforms such as the RK3566, RK3568, RK3576, and RK3588 address a range of performance needs, from embedded control to AI edge computing and advanced multimedia applications.

3. Memory and Storage

Define the required memory and storage configuration before PCB design.

Memory and storage choices can affect PCB layout, power consumption, system performance, and overall cost.

4. Interfaces and Connectivity

Identify every interface the finished product requires. This is especially important for industrial and IoT motherboards.

Typical interfaces include:

• USB 2.0 / USB 3.0
• HDMI / DisplayPort / MIPI DSI
• Ethernet
• Wi-Fi / Bluetooth
• RS232 / RS485 / UART
• CAN Bus
• GPIO / I2C / SPI
• MIPI CSI camera interfaces
• Audio input and output
• PoE, if required

Also specify the number of ports, connector types, pin assignments, and whether any interfaces require expansion.

5. Display and Touchscreen Requirements

For products that include a display, provide the following information:

• Screen size and resolution.
• Display interface, such as MIPI, LVDS, eDP, HDMI, or RGB.
• Touchscreen technology: capacitive or resistive.
• Brightness and viewing angle.
• Number of displays supported.
• Required display orientation and multi-screen functionality.

Providing the display model or its datasheet can help the engineering team assess compatibility at an early stage.

6. Operating System and Software

Hardware and software development should be planned together.

Specify:

Operating system, such as Android, Ubuntu, Debian, Buildroot, or Windows, based on platform compatibility.

• Required OS version and kernel.
• Device drivers and peripheral support.
• Boot time and startup behavior.
• BSP and SDK requirements.
• Application software and API integration needs.
• OTA update and remote management requirements.

For OEM projects, clarify whether you require a standard OS image, customized firmware, SDK documentation, or complete software integration.

7. PCB Dimensions, Mechanical Design, and Power Requirements

Mechanical and electrical requirements should be documented clearly.

• PCB and mechanical design
• Specify the board dimensions and thickness.
• Identify mounting-hole and connector locations.
• Define component-height limits.
• Describe cooling and heat-dissipation requirements.
• State enclosure dimensions and installation constraints.

Power requirements

• Specify the input-voltage range.
• State power consumption.
• Define standby-power requirements.
• Identify the power-connector type.
• Describe required protection measures.
• Note battery or PoE support, where applicable.

Documenting these details helps prevent integration issues during prototype testing.

8. Environmental and Reliability Requirements

For industrial and commercial products, specify the anticipated operating conditions.

Consider:

• Operating and storage temperature ranges.
• Humidity range.
• Vibration and shock requirements.
• System-level protection against dust and moisture.
• EMC and ESD requirements.
• Expected duration of continuous operation.
• Identify any required certifications or test standards at the start of the project.

9. Prototype, Testing, and Mass Production

An OEM motherboard specification should also outline the development and production plan.

Confirm:

• Prototype quantity.
• Functional testing requirements.
• Performance and stability testing.
• Required test reports.
• Pilot production quantity.
• Target mass production volume.
• Estimated annual demand.
• Packaging and delivery requirements.

Discussing these details early enables manufacturers to plan component sourcing, production capacity, and quality control.

10. Project Timeline and Customization Scope

Finally, clarify the expected development schedule and responsibilities.

Project Stage	Key Deliverables
Requirement review	Technical specification confirmation
Hardware design	Schematic and PCB design
Prototype	Engineering samples
Software development	BSP, drivers, and OS adaptation
Testing	Functional and reliability verification
Mass production	PCBA and finished motherboard delivery

Also specify which components need customization, including the PCB layout, RAM, storage, interfaces, firmware, enclosure, and branding.
