Questions
How big is the FTUno PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FTUno use?
60 parts, built around the ATMEGA328P-AU, CH340C, ME6217C33M5G and SPX1117M3-L-5-0/TR. 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 FTUno KiCad files?
From the HackableElectronics/FTUno repository on GitHub, at the commit this page was made from: the board is ftuno.kicad_pcb and its schematic ftuno.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FTUno 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).
