Questions
How big is the WheelSensor PCB?
It measures 49.9 × 49.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the WheelSensor use?
28 parts, built around the AMS1117-3.3. 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 WheelSensor KiCad files?
From the WilliamLim781/PCB_practice repository on GitHub, at the commit this page was made from: the board is analogbreakout/WheelSensor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the WheelSensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask WilliamLim781 before reusing the design.
