Brad Denby designed this chipsat dev board for low-power, embedded computing in space that is one of the winners of the Take Flight with Feather contest:
Chipsat development board for low-power, embedded computing in space
Junebug is a cutting-edge addition to the Feather ecosystem. It acts as a development board for chipsats – an emerging class of space system. It offers unique support for batteryless, intermittent computing. The FPU, DSP instructions, and storage space allow advanced sensor data processing with ML. Junebug is easy to manufacture, with parts selected to allow hand-assembly.
The schematic, PCB design, Gerber and Drill files, bill of materials, and other files are provided in the linked GitHub repository.
