Questions
How big is the Esp32-poe PCB?
It measures 123.9 × 35.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Esp32-poe use?
83 parts, built around the ESP32-WROOM-32E, TPS54560BDDA, HY931147C and LAN8720A-CP. 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-poe KiCad files?
From the Whitebowfr/esp32-poe repository on GitHub, at the commit this page was made from: the board is esp32_POE.kicad_pcb and its schematic esp32_POE.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32-poe design in my own project?
Its repository states no licence, so its author keeps all rights: ask Whitebowfr before reusing the design.
