Olimex ESP32-POE-ISO-EA Development Board

The Olimex ESP32-POE-ISO-EA is an ESP32-powered WiFi/BLE/Ethernet development board with an external antenna, Power-Over-Ethernet, galvanic isolation and LiPo charging.

ESP32-POE-ISO-EA has 3000VDC galvanic insulation from the Ethernet powering. It is the perfect addition to any project that requires connectivity and is recommended hardware on the ESPHome Ready-Made projects page for a Bluetooth Proxy.

The PoE is currently handled by a TPS2375PW chip that is IEEE 802.3-compliant, including pre-standard (legacy) PoE support. The 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.

ESP32-POE-ISO-EA has ESP32-WROOM-32UE module with U.FL connector and external antenna attached, which can be panel mounted. the board can operate in the commercial temperature range of 0-70C.

The board supports LiPo charging with a JST-PH connector for your LiPo battery and includes a microSD slot.

We also stock the Olimex ESP32-POE-ISO-WROVER variant.
