Questions
How big is the Bpod PCB?
It measures 41 × 96 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bpod use?
59 parts, built around the ESP32-S2, ESP32-S2-WROOM-I-N4, AP2112K-3.3 and S8050 J3Y. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Bpod KiCad files?
From the vk2gpu/bpod repository on GitHub, at the commit this page was made from: the board is hardware/bpod/bpod.kicad_pcb and its schematic hardware/bpod/bpod.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bpod design in my own project?
Its repository states no licence, so its author keeps all rights: ask vk2gpu before reusing the design.
