Olimex ESP32-POE Development Board

The Olimex ESP32-PoE is an ESP32-powered WiFI/BLE/Ethernet development board with a Power-Over-Ethernet feature. It is the perfect addition to any project that requires connectivity.

The PoE is currently handled by a TPS2375PW chip that is IEEE 802.3-compliant, including pre-standard (legacy) PoE support. PoE powering requires at least 37V DC to operate successfully. The board takes power from the Ethernet cable and can be expanded with sensors and more – the perfect solution for Internet-of-Things projects!

This board also features a LiPo battery connector and charger, MicroSD slot and RESET/user-programmable buttons. A micro-USB connection handles power and programming (be sure to grab a micro-USB cable as one isn’t included).

Important: This board has no galvanic isolation from the 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).
