Questions

How big is the ESP32-Temp PCB?

It measures 62.2 × 43.3 mm and has 4 copper layers, 4.69 mm thick.

What parts does the ESP32-Temp use?

71 parts, built around the 74HC245D, ESP32-S3-WROOM-1-N4R2, AP2112K-3.3 and WS2812B. 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 ESP32-Temp KiCad files?

From the pratapkaronde/ESP32Board repository on GitHub, at the commit this page was made from: the board is ESP32-Temp.kicad_pcb and its schematic ESP32-Temp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the ESP32-Temp design in my own project?

Its repository states no licence, so its author keeps all rights: ask pratapkaronde before reusing the design.
