IN BRIEF

The CM4NANO-B is designed for the Compute Module 4 and provides impressive performance in a small package. The connectivity is curated, although we’re missing USB3 and multiple CSI/DSI connectors. The Raspberry Pi GPIO is squeezed into the board and this is most welcome for electronics projects.

The Compute Module 4-NANO-B is an enticing prospect. It’s roughly the same size as a Raspberry Pi Zero 2 W, but with the power of a Pi 4. Disposing of the SODIMM form-factor found in previous modules, the CM4 has connectors for HDMI, GPIO, power and storage. To get the most from the CM4 you need a breakout board. Waveshare’s CM4-NANO-B is a breakout board for the CM4 that provides many of the features found in the Raspberry Pi 4, but at half of its size.
