Questions
How big is the Opod PCB?
It measures 45 × 50 mm and has 4 copper layers, 1 mm thick.
What parts does the Opod use?
114 parts, built around the BQ25895RTW, MTCH6102-I/MV, TPS7A0518PDBV and TS3USB221RSER-TP. 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 Opod KiCad files?
From the Keyaan-07/OPod repository on GitHub, at the commit this page was made from: the board is hardware/opod.kicad_pcb and its schematic hardware/audio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Opod design in my own project?
Its repository states no licence, so its author keeps all rights: ask Keyaan-07 before reusing the design.
