The Mini Base Board (A) is a compact carrier board designed for the Raspberry Pi Compute Module 5 (CM5). It supports all CM5 variants — both Lite and eMMC — and provides a rich set of interfaces including dual HDMI output, USB 3.2, Gigabit Ethernet, PCIe, and a 40-pin GPIO header.
The board measures just 85 × 56 mm, making it suitable for embedded applications, custom mini computers, media centres, and industrial control systems. A cooling fan and PWM connector are included to keep the CM5 running within optimal temperatures.
Key Features
- CM5 Compatible – Socket for all Raspberry Pi Compute Module 5 variants (Lite and eMMC)
- Dual HDMI Output – Two HDMI ports supporting 4K displays
- USB 3.2 Gen 1 – 2× USB Type-A ports (up to 5 Gbps)
- USB 2.0 – 2× additional ports via 6-pin 1 mm FFC connector
- Gigabit Ethernet – RJ45 connector supporting 10/100/1000 Mbps
- PCIe Interface – Expansion for NVMe SSDs, network cards, and other PCIe devices
- 40-Pin GPIO Header – Standard Raspberry Pi GPIO pinout
- Dual MIPI Interfaces – DSI (display) and CSI (camera) connectors
- TF Card Slot – For CM5 Lite variants without onboard eMMC
- Cooling Fan Included – 4-pin JST-SH PWM connector for active cooling
- Flexible Power – 5 V / 5 A DC input
- Mounting Options – Wall-mount brackets and rail-mount buckle included
Specifications

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- DSI
- DSI stands for Display Serial Interface, a high-speed connection commonly used to send video data from a computer board to a display. It matters because DSI signals are not simple GPIO wires, so the cable, connector, and signal routing need to match the display interface.
- eMMC
- Embedded MultiMediaCard is built-in flash storage soldered onto a board, similar in purpose to an SD card but integrated. It matters because it holds the operating system and files without needing a separate memory card.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- HDMI
- HDMI is a common digital video and audio connection used by computers, media players, and many displays. If a display kit has HDMI input, it is usually much easier to test with a single-board computer because it can act like a normal monitor.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- MIPI
- MIPI is a high-speed display and camera interface often used inside phones, tablets, and embedded devices. It matters because raw MIPI displays usually need special driver hardware or software support, unlike plug-and-play HDMI screens.
- NVMe
- A high-speed storage standard commonly used by modern SSDs. NVMe support matters if you want faster storage for large AI models, video files or operating system images than a typical microSD card can provide.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- RJ45
- The common plug and socket style used for wired Ethernet network cables. If a board has an RJ45 connector, you can usually plug it into standard Ethernet cabling without making a custom connector.
