Questions
How big is the Comet pcb PCB?
It measures 61 × 38 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Comet pcb use?
90 parts, built around the AS5055 AB, DRV8835DSS, ICM-20600 and TLV75733PDBV. 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 Comet pcb KiCad files?
From the Teruru-52/comet-pcb repository on GitHub, at the commit this page was made from: the board is v1.0/main/main.kicad_pcb and its schematic v1.0/encoder/encoder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Comet pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask Teruru-52 before reusing the design.
