Questions
How big is the P3-cellular module PCB?
It measures 42 × 55.8 mm and has 4 copper layers, 1 mm thick.
What parts does the P3-cellular module use?
54 parts, built around the USBLC6-2SC6, 06035A330KAT2A, C0603C104K3RAC and CL32B226MOJNNNE. 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 P3-cellular module KiCad files?
From the themainframe/p3-cellular-module repository on GitHub, at the commit this page was made from: the board is p3-cellular-module.kicad_pcb and its schematic cellular-modem.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the P3-cellular module design in my own project?
Its repository states no licence, so its author keeps all rights: ask themainframe before reusing the design.
