Questions
How big is the Pb mobo final PCB?
It measures 58 × 34.5 mm and has 2 copper layers, 0.89 mm thick.
What parts does the Pb mobo final use?
49 parts, built around the DLF162500LT-5028A1, AMS1117-1.8, AMS1117-3.3 and ICM-20948. 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 Pb mobo final KiCad files?
From the anbridge/pb-elec-design repository on GitHub, at the commit this page was made from: the board is kicad/pb_mobo_final/pb_mobo_final.kicad_pcb and its schematic kicad/battery_charger/battery_charger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pb mobo final design in my own project?
Its repository states no licence, so its author keeps all rights: ask anbridge before reusing the design.
