Questions
How big is the ESP32Board PCB?
It measures 89.7 × 50.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32Board use?
91 parts, built around the ESP32-WROOM-32E, CH340K, WS2812B-2020 and BSS138. 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 ESP32Board KiCad files?
From the fTomo-robot/ESP32Board repository on GitHub, at the commit this page was made from: the board is ESP32Board.kicad_pcb and its schematic ESP32Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask fTomo-robot before reusing the design.
