Questions
How big is the Bed mainboard pcb PCB?
It measures 80 × 110 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bed mainboard pcb use?
33 parts, built around the OPA2277U and IRF9540NS. 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 Bed mainboard pcb KiCad files?
From the arrowtip/bed-mainboard_pcb repository on GitHub, at the commit this page was made from: the board is mainboard.kicad_pcb and its schematic mainboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bed mainboard pcb design in my own project?
Its repository publishes it under the MPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
