Mini Base Board (A) for Raspberry Pi Compute Module 4

This Mini Base Board (A) for the Raspberry Pi Compute Module 4 is a compact CM4 breakout option offering a good set of features with a small footprint.

Two versions of this board are available - Lite (A) or Full (B). This is the Lite (A) version which does not include a Real-time Clock (RTC) or fan speed control.

With its M.2 slot, MicroSD card slot, dual-CSI ports and a host of other features, it's a great base for any CM4 project - and a more affordable option if you don't need the RTC/fan control functionality of the full version.

Note: Compute Module and M.2 SSD not included
