Questions
How big is the Librem5 mainboard PCB?
It measures 74.3 × 65.6 mm and has 10 copper layers, 1.28 mm thick.
What parts does the Librem5 mainboard use?
1,296 parts, built around the LM3560TLX, BQ25895RTW and DTC123JUA. 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 Librem5 mainboard KiCad files?
From the gralco/l5-schematic repository on GitHub, at the commit this page was made from: the board is CAD/KiCad/librem5_mainboard/librem5_mainboard.kicad_pcb and its schematic CAD/KiCad/librem5_mainboard/02_POWER_TREE.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Librem5 mainboard 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).
