Raspberry Pi Compute Module 4 IO Board
Exposing every interface from Raspberry Pi Compute Module 4, the Compute Module 4 IO Board provides a development platform and reference base-board design for our most powerful Compute Module yet.
- External +12V PSU
- 2 x full-size HDMI 2.0 connectors
- Gigabit Ethernet RJ45 with POE support
- 2 x USB 2 socket, with header for two more sockets
- Micro USB socket for updating the CM4 and micro SD card socket for CM4Lite modules
- PCIe Gen 2 socket
- Standard Fan connector
- External power connector (+5V, +12V)
- 2 x MIPI DSI display FPC connectors, 2 x MIPI CSI-2 camera FPC connectors
- RTC with battery socket and ability to wake up CM4
The IO board is designed to allow you to create systems quickly using off-theshelf parts such as HATs and PCIe cards, which might include NVMe, SATA, networking, or USB. The major user connectors are located along one side to make enclosures simple.
Compute Module 4 IO Board also provides an excellent way to prototype systems using the Compute Module 4.
he Compute Module 4 IO Board is a companion board for Raspberry Pi Compute Module 4 (supplied separately). It is designed for use both as a development system for Compute Module 4 and as an embedded board integrated into end products.
