Cmio
Cmio is an open source Raspberry Pi PCB design by deltabeard: a 2-layer, 72.4 × 26.6 mm board with 43 components (29 distinct parts). It is built around the AP3417BK-ADJTRG1, SP6203EM5-L-2-8, AP2401MP-13.
Custom Raspberry Pi Compute Module (1/3) IO Board
Note that this circuit is currently untested, as such I cannot guarantee that it will function correctly.
This is a custom Raspberry Pi Compute Module IO Board. Designed for low cost production, and a minimal set of components.
Because low cost production was the main focus of the project, this Compute Module IO board only has a subset of features in comparison to the official version. However, whilst the official version costs £115, this design aims to produce a Compute Module IO board that can be manufactured (PCB fabrication, BOM, et al) under £30.
