Questions
How big is the Esp32-dev module PCB?
It measures 51.5 × 27.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32-dev module use?
32 parts, built around the CH340C, AMS1117-3.3, SS8050 and 1N5819WS. 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-dev module KiCad files?
From the toufiqnuur/esp32-dev-module repository on GitHub, at the commit this page was made from: the board is esp32-dev module.kicad_pcb and its schematic esp32-dev module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32-dev module design in my own project?
Its repository states no licence, so its author keeps all rights: ask toufiqnuur before reusing the design.
