IoT in pure form

ESP32 is IoT WiFi/BLE/Ethernet development board with Power Over Ethernet IEEE 802.3 compliant, including pre-standard (legacy) PoE support based on Si3402-B chipset. Perfect solution for connection of IoT sensors and actuators taking power from Ethernet cable.

This module is better version of ESP32-POE - it is equiped with pigtail and external antenna. Better range and now, with ESP32-POE-EA You can place module inside metal and have good WiFi connectivity with external WiFi antenna (both pigtail and antenna included with module)

As for October 2024 we sell boards in revision L or later (so with mount holes).

No galvano isolation between USB and PoE line!

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.
