Questions
How big is the Bycicle speedometer v2 PCB?
It measures 58 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bycicle speedometer v2 use?
23 parts, built around the ESP-12E. 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 Bycicle speedometer v2 KiCad files?
From the clovisf/bycicle-speedometer-v2 repository on GitHub, at the commit this page was made from: the board is bycicle-speedometer-v2/bycicle-speedometer-v2.kicad_pcb and its schematic bycicle-speedometer-v2/bycicle-speedometer-v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bycicle speedometer v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask clovisf before reusing the design.
