Questions
How big is the Bike PCB?
It measures 54 × 35 mm and has 4 copper layers, 1.65 mm thick.
What parts does the Bike use?
67 parts, built around the CP2104EK, ESP32-WROOM-32, APTD3216SECK and AP2112K-3.3. 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 Bike KiCad files?
From the InfinityTech100/Bike-Mini-speedo repository on GitHub, at the commit this page was made from: the board is Hardware/Bike/Bike.kicad_pcb and its schematic Hardware/Bike/Bike.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bike design in my own project?
Its repository states no licence, so its author keeps all rights: ask InfinityTech100 before reusing the design.
