Questions
How big is the Bitforge PCB?
It measures 343 × 121 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bitforge use?
170 parts. 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 Bitforge KiCad files?
From the LegendPlayz83/Bitforge repository on GitHub, at the commit this page was made from: the board is PCB/Bitforge.kicad_pcb and its schematic PCB/Bitforge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bitforge design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
