Olimex ESP32-POE-ISO-WROVER Development Board

The Olimex ESP32-PoE-ISO is an ESP32-powered WiFi/BLE/Ethernet development board with Power-Over-Ethernet. The ESP32-POE-ISO has 3000VDC galvanic insulation from Ethernet powering.

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. There’s also a LiPo battery connector and charging circuit onboard – it’s the perfect solution for Internet-of-Things projects!

Olimex offer a range of versions of this board. This is the ESP32-POE-ISO-WROVER version, which comes with an ESP32-WROVER-E with 4MB flash and 8MB PSRAM. Notice that the WROVER module requires two extra pins for the PSRAM – some software changes related to Ethernet and I2C might be required.

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