ESP32-POE-ISO is OSHW certified Open Source Hardware with UID BG000021

ESP32-PoE is an IoT WIFI/BLE/Ethernet development board with Power-Over-Ethernet feature. The Si3402-B chip is IEEE 802.3-compliant, including pre-standard (legacy) PoE support. 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-WROOM-32 - WiFi and bluetooth module
  • Low power design - 200uA consumption in deep sleep
  • Ethernet 100Mb interface with IEEE 802.3 PoE support
  • 3000VDC galvanic insulation between the PoE Ethernet part and board's power supply circuit
  • Micro USB connector for ESP32 programming
  • MicroSD card working in 1 bit mode (3 more GPIOs)
  • LiPo battery charger with LiPo battery connector
  • Battery level monitor pin on ADC
  • External power supply detection pin on ADC
  • DC-DC 2W 5V/400mA
  • UEXT connector
  • User button
  • Reset button
  • Two extension connectors, 0.1" step spaced at 1"
  • PCB dimensions: (100 x 28)mm ~ (3 x 1)"



  • ESP32-PoE-ISO doesn't work well with bauds over 115200. What to do?
  • Some older drivers might have wrong timings, causing worse throughput. Download and install the latest drivers for CH340. If you are using Linux make sure to try with these drivers: high-speed driver for Linux 
  • I power the board from the Ethernet connector. What current do I have avialbe for additional circuits?
  • The isolated DCDC that we use provides up to 2W, this means 400mA @ 5V, 100mA are reserved for the battery charge (available if no battery is connected) and 100mA are provided for ESP32, which leaves up to 200mA @ 5V for your additional circuit.
