Questions
How big is the Footswitch PCB?
It measures 93 × 35.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Footswitch use?
70 parts, built around the ATMEGA328P-AU, NRF24L01P-R, LT1944EMS#PBF and BSS214NWH6327XTSA1. 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 Footswitch KiCad files?
From the jvsalo/footswitch repository on GitHub, at the commit this page was made from: the board is kicad/footswitch.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Footswitch 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).
