Note

Don't power via X635 USB-C socket when connect another PC to X635 USB-A.
To enable the CM4 to be updated via rpiboot, You have to put a jumper over the pins of "nBOOT" and "GND" on the 6-pin header.
Please use only the screws(M2x3mm) for mounting the SSD come with this kit. Other screw size(length>3mm) will damage your Micro-SD card or the card socket!!!

Overview

The X635 is a ultra-compact carrier board specifically designed for the Raspberry Pi compute module 4.

It supports M.2 NVMe SSD expansion board which offers an easy and fast way to create storage solution. At the same time, it adds HDMI to CSI-2 bridge that converts HDMI stream to MIPI CSI-2 TX. The CM4 has been designed without video streaming input port except CSI-2 for camera input, and this carrier board can be used with CM4 in several applications that required Video Input.
