Questions
How big is the Belle PCB?
It measures 44.4 × 44.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Belle use?
26 parts, built around the 74AHC1G14GV and AP2112K-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 Belle KiCad files?
From the sayanee/belle repository on GitHub, at the commit this page was made from: the board is hardware/Belle.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Belle design in my own project?
Its repository states no licence, so its author keeps all rights: ask sayanee before reusing the design.
