Questions
How big is the Baconbits PCB?
It measures 55 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Baconbits use?
64 parts, built around the FT230XQ-R, MCP23S18-E/MJ, MMA8452QR1 and TPD4S012DRY. 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 Baconbits KiCad files?
From the e-ale/BaconBitsCapeHW repository on GitHub, at the commit this page was made from: the board is baconbits.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Baconbits design in my own project?
Its repository states no licence, so its author keeps all rights: ask e-ale before reusing the design.
