Questions
How big is the Gps unit coin cell PCB?
It measures 57 × 27 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Gps unit coin cell use?
28 parts, built around the SAM-M10Q-00B, MCP1700T-3302E/TT(MS), MS621FE-FL11E and A-1JB. 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 Gps unit coin cell KiCad files?
From the KingJacker/gps_lora repository on GitHub, at the commit this page was made from: the board is gps_unit/gps_unit_coin-cell.kicad_pcb and its schematic gps_unit/gps_unit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gps unit coin cell design in my own project?
Its repository states no licence, so its author keeps all rights: ask KingJacker before reusing the design.
