Questions
How big is the BADGER v41 PCB?
It measures 101.6 × 78.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BADGER v41 use?
117 parts, built around the BQ32000D, TXS0108EPW, 2N7002KW and BSS84W. 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 BADGER v41 KiCad files?
From the wyolum/BADGEr repository on GitHub, at the commit this page was made from: the board is Kicad/BADGER_v41.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BADGER v41 design in my own project?
Its repository states no licence, so its author keeps all rights: ask wyolum before reusing the design.
