Questions
How big is the Fanctrl PCB?
It measures 40 × 86 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Fanctrl use?
33 parts, built around the ESP32-C3-WROOM-02-H4, SK22 and YJM04N10A. 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 Fanctrl KiCad files?
From the burgrp/accuwatt repository on GitHub, at the commit this page was made from: the board is fanctrl/board/fanctrl.kicad_pcb and its schematic fanctrl/board/driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fanctrl design in my own project?
Its repository states no licence, so its author keeps all rights: ask burgrp before reusing the design.
