Raspberry Pi Compute Module 4 (CM4) Base Carrier

Simple carrier board for the Raspberry Pi Compute Module 4. It provides power to the module through the USB-C connector (power only, no data), USB client mode (host mode is not supported), Qwiic/Stemma connector for I2C lines, SPI, UART, and power/activity LEDs.

Feel free to modify this design for your own application. This PCB is not intended to be an end product but rather a demo to get people started making their own carrier boards for the CM4.

Note that USB traces were calculated for a 2-layer board with a 1.6mm height.
