After seeing t0mpr1c3’s proto cape, I thought it would be worth to share my cape prototyping board, designed a while ago for BB White. It has space for EEPROM chip, so it can be used also for testing prototypes of capes which will later will go into production. To make life easier, the board has detachable “wings” with descriptions of the signals on the connectors.
The design files and gerbers are posted on github
I also shared libraries with schematic symbols and PCB modules for kicad for BB White and BBB. The BBB version of the cape is “in the works” but needs final touch-ups before I can share the design.
