This Proto Cape kit is designed for the Beagle Bone and Beagle Bone Black, allowing users to add custom circuitry. The PCB mounts conveniently on top of the Beagle Bone without obstructing the Ethernet port. It features breakout connections to both 46-pin headers with clear numbering, along with strips for accessing the 5V and 3V power supplies. The kit includes a double-sided FR4 PCB, three header sticks, and pieces for SMT breakout connections for SOIC-8 and SOT-23 packages. Installation involves placing the headers into the Beagle Bone and soldering the PCB in place.
