CM4 Maker Board

Adapter board for all versions of Raspberry Pi Compute Module 4. The board breaks out all GPIOs, periphials and adds several additional functions, like RTC, DC-jack (7-18VDC), a summer, Grove connectors, status LEDs for GPIO pins and boot-/ power-switches. In short, a very versatile and capable evaluation board for Compute Module 4.
