What is it?

This is an open-source development board for Esp32 with Ethernet and passive PoE support that was funded on Kickstarter.

Why did I make it?

I made it because I often prefer Ethernet over WiFi in my projects. In my humble opinion, Ethernet is more stable and simpler to use(plug and play), using PoE and powering the board via Ethernet cable makes it even more attractive. Standard active PoE uses 48V and requires special adapter. Passive PoE does not require one, and can be powered using cheap PoE injectors. Unfortunately there were no Esp32 with passive PoE support at the market, so I made one:) I also made 2 other versions of this board: Esp32-Stick-PoE-A and Esp32-Stick-Eth, which have the same MCU, dimensions and pinout for projects where you really need active PoE(Esp32-Stick-PoE-A) or don't need PoE at all(Esp32-Stick-Eth).

What makes it special?

Pin-to-pin compatibility with other Esp32-Stick boards and passive PoE support!

Here are other features too:

  • 17 pins are not used by Ethernet are available for programming
  • USB Type-C
  • Esp32-Stick-Poe-P has a wide range of input PoE voltages. (9V-57V). With this board you can choose any passive PoE injector you like, it is completely up to your design
  • Esp32-Stick-Poe-P has 5V 2A output, so you can power a lot of additional periphery.
  • Esp32-Stick boards are fully programmable in Arduino and are supported in ESPHome home automation environment(Examples are available on Github)
  • No external USB-UART converter is required, ready for plug-and-play programming!
  • All the Esp32-Stick boards have the same length and width so they can easily be replaced with one another.
  • Any code written for one board is compatible with another because they share the same CPU and pinout.


  • ESP32-Wroom module.
  • USB-C connector.
  • 17 Pins are available.
  • LAN8720A chip for Ethernet.
  • LM2596HV for Passive POE(PoE-P).
  • CH340G USB-UART converter.
  • USER-Led(GPIO2).
  • Reset button and User button(GPIO0).
  • Accepts power through: USB, External source (3.3V-5V), Passive POE(9-57V)
