Questions
How big is the Bike ometer PCB?
It measures 68 × 35.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bike ometer use?
60 parts, built around the STM32L063C8U6, MIC2288YD5-TR, RT8097AHGB and LCD-S2X1C50TR. 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 ometer KiCad files?
From the antonloof/bike_ometer repository on GitHub, at the commit this page was made from: the board is kicad/kicad.kicad_pcb and its schematic kicad/kicad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bike ometer design in my own project?
Its repository states no licence, so its author keeps all rights: ask antonloof before reusing the design.
