Questions
How big is the GolfSpeedSensor PCB?
It measures 126.9 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GolfSpeedSensor use?
47 parts, built around the ATMEGA32U4-AU, 74HC595 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 GolfSpeedSensor KiCad files?
From the ebur644/GolfSpeedSensorProject repository on GitHub, at the commit this page was made from: the board is PCB_Design/GolfSpeedSensor.kicad_pcb and its schematic PCB_Design/GolfSpeedSensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GolfSpeedSensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask ebur644 before reusing the design.
