Questions
How big is the Padv1 PCB?
It measures 146.6 × 63.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Padv1 use?
79 parts, built around the ESP32-C3-WROOM-02-H4, CP2102N-A02-GQFN20, COM-09032 and USBLC6-2SC6. 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 Padv1 KiCad files?
From the OliwerL/gamepadv1 repository on GitHub, at the commit this page was made from: the board is padv1.kicad_pcb and its schematic User_intereface.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Padv1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask OliwerL before reusing the design.
