Questions
How big is the Digirig mobile PCB?
It measures 22.8 × 36 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Digirig mobile use?
64 parts, built around the ADM3101EARQ, CM108B, CP2102N-A02-GQFN24 and USB2412-DZK-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 Digirig mobile KiCad files?
From the softcomplex/Digirig-Mobile repository on GitHub, at the commit this page was made from: the board is electric/digirig-mobile/digirig-mobile.kicad_pcb and its schematic electric/digirig-mobile/digirig-mobile.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Digirig mobile 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).
