Questions
How big is the Mobile Dev Board PCB PCB?
It measures 29.9 × 58.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mobile Dev Board PCB use?
40 parts, built around the AP2112K-3.3 and BQ24075RGT. 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 Mobile Dev Board PCB KiCad files?
From the jpatrick5402/Mobile-Dev-Board repository on GitHub, at the commit this page was made from: the board is Mobile Dev Board PCB/Mobile Dev Board PCB.kicad_pcb and its schematic Mobile Dev Board PCB/Mobile Dev Board PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mobile Dev Board PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask jpatrick5402 before reusing the design.
