Questions
How big is the KeeBar PCB?
It measures 376 × 86.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KeeBar use?
141 parts, built around the RP2040-ZERO and 1N4148W. 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 KeeBar KiCad files?
From the ymkn/KeeBar repository on GitHub, at the commit this page was made from: the board is KiCad/KeeBar_PCB/KeeBar.kicad_pcb and its schematic KiCad/KeeBar_PCB/KeeBar.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the KeeBar 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).
