ESP32-PoE is an IoT WIFI/BLE/Ethernet development board with Power-Over-Ethernet feature. The PoE is handled by TPS2375PW chip (Si3402-B in older revisions) that is IEEE 802.3-compliant, including pre-standard (legacy) PoE support. The PoE chip requires at least 37V DC to operate successfully. The board takes power from the Ethernet cable and can be expanded with sensors and actuators. Perfect solution for Internet-of-Things projects.
ESP32-POE-ISO has 3000VDC galvanic insulation from Ethernet power.
ESP32-POE-ISO-EA has module with U.FL connector and external antenna attached, which allow mounting in metal box.
ESP32-POE-ISO and ESP32-POE-ISO-EA are with commercial temperature range 0-70C
ESP32-POE-ISO-IND and ESP32-POE-ISO-EA-IND are functionally identical, but has all components qualified to work in industrial temperature grade -40+85C
