Questions
How big is the WiredToBleKeyBoardPCB PCB?
It measures 99.5 × 28.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the WiredToBleKeyBoardPCB use?
43 parts, built around the ESP32-S3-WROOM-1-N8, USBLC6-2SC6, AP2112K-3.3 and IP5306-I2C. 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 WiredToBleKeyBoardPCB KiCad files?
From the bhaveshkys/wiredToBleKeyBoardPCB repository on GitHub, at the commit this page was made from: the board is test.kicad_pcb and its schematic test.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WiredToBleKeyBoardPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask bhaveshkys before reusing the design.
