Questions
How big is the Encoder driver PCB?
It measures 78.9 × 55.9 mm and has 4 copper layers, 4.69 mm thick.
What parts does the Encoder driver use?
44 parts, built around the CA-IS3720HS, CA-IS3721CHS, BZV55C6V2 and SI2319CDS. 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 Encoder driver KiCad files?
From the owhite/QS165_encoder repository on GitHub, at the commit this page was made from: the board is AS5048_isolation/encoder_driver.kicad_pcb and its schematic AS5047_atmega328p/atmega328.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Encoder driver design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
