Questions
How big is the SAE Cellular Module PCB?
It measures 55 × 85 mm and has 4 copper layers, 1.6 mm thick.
What parts does the SAE Cellular Module use?
152 parts, built around the NRF9151-LACA-R, SAM-M10Q-00B, TPS54202DDC and 23K256T-I/ST. 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 SAE Cellular Module KiCad files?
From the ephrenm/VehiCell repository on GitHub, at the commit this page was made from: the board is SAE-Cellular-Module/SAE Cellular Module.kicad_pcb and its schematic SAE-Cellular-Module/2_NRF9151.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SAE Cellular Module design in my own project?
Its repository states no licence, so its author keeps all rights: ask ephrenm before reusing the design.
