Questions
How big is the ESP32-PoE ISO Rev N1 PCB?
It measures 28 × 98.2 mm and has 4 copper layers, 1.58 mm thick.
What parts does the ESP32-PoE ISO Rev N1 use?
146 parts, built around the ESP32-WROOM-32E-N4, IRLML6402TRPBF and SMBJ5.0A. 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 ISO Rev N1 KiCad files?
From the OLIMEX/ESP32-POE-ISO repository on GitHub, at the commit this page was made from: the board is HARDWARE/ESP32-PoE-ISO-Rev.N1/ESP32-PoE-ISO_Rev_N1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-PoE ISO Rev N1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask OLIMEX before reusing the design.
