Raspberry Pi Compute Module IO Board V3

Sold out

Comprehensive information on the Compute Modules is available in the relevant hardware documentation section of our website, and includes a datasheet and schematics.

With the launch of CM3 and CM3 Lite, we are not obsoleting the original Compute Module; we still see this as a valid product in its own right, being a lower-cost and lower-power option where the performance of a CM3 would be overkill.

CM3 and CM3L are priced at $30 and $25 respectively (excluding tax and shipping), and this price applies to any size order. The original Compute Module is also reduced to $25. Our partners RS and Premier Farnell are also providing full development kits, which include all you need to get started designing with the Compute Module 3.

The CM3 is largely backwards-compatible with CM1 designs which have followed our design guidelines. The caveats are that the Module is 1mm taller than the original Module, and the processor core supply (VBAT) can draw significantly more current. Consequently, the processor itself will run much hotter under heavy CPU load, so designers need to consider thermals based on expected use cases.
