Questions
How big is the ESP32S2 WS2812 v0.5 PCB?
It measures 43.5 × 29 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32S2 WS2812 v0.5 use?
35 parts, built around the 74AHC1G125GW, ESP32-S2-MINI-2-N4, TLV75533PDBV and PTS12066V050. 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 ESP32S2 WS2812 v0.5 KiCad files?
From the GerritMihu/Stiftehalter repository on GitHub, at the commit this page was made from: the board is KiCad/ESP32S2_WS2812_v0.5.kicad_pcb and its schematic KiCad/ESP32S2_WS2812_v0.5.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32S2 WS2812 v0.5 design in my own project?
Its repository states no licence, so its author keeps all rights: ask GerritMihu before reusing the design.
