ESP32-POE Open Source Hardware IoT development board with WiFi/BLE/100Mb Ethernet with 802.3 POE is in stock!


ESP32-POE board is now in stock. The prices start from EUR 14.36 for 50 pcs order.

This board offers Open Source Hardware / FOSS solution and building block for distributed sensor network with power over existing LAN infrastructure.

Possible use cases are Home automation, Industrial machine logging, remote environmental monitoring, access control, remote displays etc.

The board contains ESP32-WROOM-32 module with WiFi/BLE and Ethernet connectivity , RESET and USER buttons, micro SD card, LiPo battery charger and LiPo connector which allow board to work even with power supply drops.

The UEXT connector on the board can be used to connect many different sensors like:

Si3402-B chipset takes care for the power over ethernet, it’s IEEE 802.3 compliant, including pre-standard (legacy).

Important notice, to keep board compact and as it’s main purpose is to connect to cloud different remote sensors there is no galvanic isolation between board and the power delivered by the LAN switch or router.

ESP32-POE has internal programming interface and you can program it with Espressif SDK or Arduino via USB cable. As the board is not galvanic isolated from the Ethernet power supply, before you connect the USB cable to your computer you should remove the Ethernet cable or you should use USB-ISO between your computer the ESP32-POE!

    Unfortunately Ethernet does not seem to work. The board is supplied with power (PoE), but nothing more happens.
