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. The board takes power from the Ethernet cable and can be expanded with sensors and actuators. Perfect solution for Internet-of-Things projects.
Important notice: ESP32-POE has no galvano isolation from Ethernet's power supply, when you program the board via the micro USB connector the Ethernet cable should be disconnected (if you have power over the Ethernet cable)! Consider using Olimex USB-ISO to protect your computer and board from accidental short circuit. Also consider instead using Olimex ESP32-PoE-ISO board which is insulated.
ESP32-POE-EA has module with U.FL connector and external antenna attached.

Ethernet 100Mb interface with IEEE 802.3 PoE support
ESP32-PoE doesn't work well with bauds over 115200. What to do?
Some older drivers might have wrong timings, causing worse throughput. Download and install the latest drivers for CH340. If you are using Linux make sure to try with these drivers: high-speed driver for Linux
What current is available when the board is powered via the Ethernet connector (PoE)?
The PoE circuit can safely provide up to 4W, i.e. 800mA @ 5V. Part of this wattage is used to power the ESP32 module, the battery charger, and other circuits part of the board design; the remaining wattage is available for additional circuits (up to around 600mA). Make sure the total current consumption does not exceed 800mA @ 5V.
