Questions
How big is the Digirig Lite PCB?
It measures 15.8 × 36.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Digirig Lite use?
54 parts, built around the GS2005ELD and MMBT5551L. 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 Lite KiCad files?
From the softcomplex/Digirig-Lite repository on GitHub, at the commit this page was made from: the board is electric/digirig-lite.kicad_pcb and its schematic electric/digirig-lite.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Digirig Lite 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).
