- Raspberry Pi Compute Module 4 I/O Board
The Raspberry Pi Compute Module 4 I/O board is the perfect compliment to get you started working the Compute Module 4 line. The Compute Module plugs right into the I/O Board and provides a multitude of inputs and outputs for prototyping or evaluation needs.
The board includes 5v and 12v power connectors and 2 USB 2.0 connectors along with headers for two additional connectors. 2 HDMI full sized HDMI connectors and 2 MIPI DSI display FPC connectors provide support for displays along with 2 MIPI CSI-2 camera FPC connectors. It features the standard 40 pin Raspberry Pi HAT I/O connector as well. On board real time clock with back-up battery provides the ability to wake up the Compute Module 4. An RJ45 Ethernet jack provides access to the Compute Module’s gigabit Ethernet and the board also includes a PCIe GEN 2 socket. Various jumper headers offer the ability to hardware disable/enable features and another header provides support for fans.

Raspberry Pi Compute Module 4 I/O Board Product Help and Resources
Core Skill: Programming
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Review from technician who is using the board
It's all good thanks. I got it connected and running last week.
I need some field data from a few customers and a little help from Mat (when he gets back) before I can continue playing with it.
A great carrier but be sure to RTFM
This I/O board is a great time saver for development of compute module based systems, but be sure to read the fancy manual or you can cause yourself some heartache (e.g. I recommend putting tape over the uSD socket if you are working with CMs with eMMC on them so you don't accidentally insert a card when you shouldn't.
The only suggestion for improvement would be switching one of the HDMI ports for a micro - they have them on the Pi4 board so I have to have both cables at my bench if I'm using both.
Great Platform for Using the RPi CM4
The CM4 I/O Board has a great selection of inputs and outputs for the RPi CM4. I found I had to press harder than I expected to get the Compute Module to seat in the I/O board, but once it was firmly seated, everything works fine. I loaded 64 Bit Ubuntu for ARM, and no problems running it headless, remote desktop, over Ethernet.
Does a good job of providing access to the CM4 Module
If you don't mind the size, this I/O Board does a good job of supporting the CM4 Modules. The only thing about this I/O Board that I didn't like was the Mezzanine connectors for the CM4 Module. Even when you think that you have the CM Module locked into the Mezzanine connectors you might not and will not know until the CM Module will not power up when power is applied to the I/O Board.
Perfect for my project!
Now, if we can just get MORE Compute Modules.....
Hi does this include power cable? if not, do you sell any power compatible with this board?(12V is preferred)
