Questions
How big is the Four way rotator PCB?
It measures 140.7 × 54 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Four way rotator use?
57 parts, built around the 74AHCT125D, ESP32-S3-WROOM-1-N8, DRV8871DDA and TPS5403D. 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 Four way rotator KiCad files?
From the jonnydyer/rotator_pcb repository on GitHub, at the commit this page was made from: the board is kicad/four_way_rotator.kicad_pcb and its schematic kicad/four_way_rotator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Four way rotator design in my own project?
Its repository states no licence, so its author keeps all rights: ask jonnydyer before reusing the design.
