Questions
How big is the Esp32 pcb PCB?
It measures 25.7 × 63 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Esp32 pcb use?
30 parts, built around the ESP32-S3-MINI-1-N8, ENS210, D3V3XA4B10LP and TLV75801PDRV. 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 pcb KiCad files?
From the LJBirch/esp32_pcb repository on GitHub, at the commit this page was made from: the board is esp32_pcb.kicad_pcb and its schematic esp32_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32 pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask LJBirch before reusing the design.
