Questions
How big is the BitMasher PCB?
It measures 60 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BitMasher use?
172 parts, built around the EFM32PG12B500F1024GM48-C, 74AVCH4T245RSVR-NT, CS42L52-CNZ and FT230XQ-R. 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 BitMasher KiCad files?
From the superkittens/BitMasher-Hardware repository on GitHub, at the commit this page was made from: the board is BitMasher/BitMasher.kicad_pcb and its schematic BitMasher/BitMasher.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BitMasher design in my own project?
Its repository states no licence, so its author keeps all rights: ask superkittens before reusing the design.
