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.

External antenna - You can place module inside metal case and still get good WiFi connectivity. Or in case You need just better range than offered by standard PCB antenna.

Galvanic isolation from Ethernet

This module has galvanic isolation, allowing to connect USB and program module when Ethernet has power enabled. This is main difference from ESP32-POE-EA.
