- Updated the BOM (and some parts) to make this compatible with PCBA from jlcpcb.com.

Questions
How big is the Bitcrane PCB?
It measures 110 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Bitcrane use?
114 parts, built around the M93C46-WDW6TP, RT9080-33GJ5, DMP3013SFV-7(ES) and LBZX84C12LT1G. 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 Bitcrane KiCad files?
From the skot/bitcrane repository on GitHub, at the commit this page was made from: the board is bitcrane.kicad_pcb and its schematic bitcrane.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bitcrane design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
