Questions
How big is the Winder PCB?
It measures 47 × 38.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Winder use?
34 parts, built around the ESP32-C3-WROOM-02-H4, MAX3485ED, RS485 and TB67H450FNG. 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 Winder KiCad files?
From the nasu8151/-2-- repository on GitHub, at the commit this page was made from: the board is winder/winder.kicad_pcb and its schematic ufo/ufo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Winder design in my own project?
Its repository states no licence, so its author keeps all rights: ask nasu8151 before reusing the design.
