From the project
ESP32 IoT development board with 100Mb Ethernet and 802.3 Power Over Ethernet (POE)
ESP32-PoE is an IoT WIFI/BLE/Ethernet development board with Power-Over-Ethernet feature.
The Si3402-B chip is IEEE 802.3-compliant, including pre-standard (legacy) PoE support.
Perfect solution for Internet-of-Things that can be expanded with sensors and actuators taking power from Ethernet cable.
Low-power design consuming less then 100uA in deep sleep mode!

ESP32-PoE Rev K: common questions
What microcontroller does the ESP32-PoE Rev K use?
The ESP32-PoE Rev K is built around the ESP32-WROVER-E, from the ESP32 family.
How big is the ESP32-PoE Rev K PCB?
The ESP32-PoE Rev K measures 28 × 80 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the ESP32-PoE Rev K?
131 components, from 73 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the ESP32-PoE Rev K design files?
From the OLIMEX/ESP32-POE repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the ESP32-PoE Rev K design in my own project?
Yes, under the terms of its Apache-2.0 license, which OLIMEX chose for the repository.
Can I test firmware for the ESP32-PoE Rev K without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
