Questions
How big is the Exbike usb hw PCB?
It measures 51.3 × 18.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Exbike usb hw use?
19 parts, built around the ATTINY24A-SSU and 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 Exbike usb hw KiCad files?
From the 03vmate/exercisebike-usb-interface repository on GitHub, at the commit this page was made from: the board is exbike-usb-hw/exbike-usb-hw.kicad_pcb and its schematic exbike-usb-hw/exbike-usb-hw.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Exbike usb hw design in my own project?
Its repository states no licence, so its author keeps all rights: ask 03vmate before reusing the design.
