Questions
How big is the DevPocket PCB?
It measures 60 × 70 mm and has 4 copper layers, 1.6 mm thick.
What parts does the DevPocket use?
143 parts, built around the CP2102-GMR, ESP32-WROOM-32UE-N4, AMS1117-3.3 and TP4056-42-ESOP8. 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 DevPocket KiCad files?
From the Hopichek/Projects repository on GitHub, at the commit this page was made from: the board is DevPocket/ECAD/DevPocket/v0.1/DevPocket.kicad_pcb and its schematic DevPocket/ECAD/DevPocket/v0.1/DevPocket.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DevPocket design in my own project?
Its repository states no licence, so its author keeps all rights: ask Hopichek before reusing the design.
