The Raspberry Pi Compute Module 3 Development Kit contains the following components:
Raspberry Pi Compute Module IO Board
This is the main development kit IO board into which the Compute Module SODIMM board is connected. It also contains all of the necessary interface ports to allow an engineer to design and test their own prototype application.
The IO board contains the following interfaces:
- Multiple GPIO interfaces on 2 60 way 0.1” Headers
- 1 x Micro USB connector type B – USB Slave
- 1 x USB connector type A – USB Host
- 2 x CSI ports for camera boards
- 2 x DSI ports for display boards
- Full size HDMI port
- Micro USB power connector
- Micro SD connector
The schematics and board design files for the Compute Module IO board have been published by the Raspberry Pi Foundation and detail the interconnection between the SODIMM socket and the interfaces on the IO board.

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.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- USB host
- A USB host is the side of a USB connection that controls attached devices, like a computer talking to a keyboard or flash drive. This matters because most microcontroller boards are normally USB devices, so adding USB host support lets them use common USB peripherals.
