Questions
How big is the SMORES PCB?
It measures 21 × 18 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SMORES use?
36 parts, built around the E73-2G4M08S1C, QMC6309, BQ24075RGT and SG-8002CE-PCB. 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 SMORES KiCad files?
From the infopcgood/SMORES repository on GitHub, at the commit this page was made from: the board is SMORES.kicad_pcb and its schematic SMORES.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SMORES design in my own project?
Its repository states no licence, so its author keeps all rights: ask infopcgood before reusing the design.
