Radxa 23W PoE

Radxa 23W PoE HAT

Radxa 23W PoE HAT is a HAT accessory designed for Raspberry Pi, Radxa ROCK 3 and 4 series, and Jetson Nano.
The 23W PoE HAT allows you to power your Raspberry Pi, ROCK 3 and 4 series or Jetson Nano using Power over Ethernet–enabled networks; for this product to be used, the network it is connected to needs to have power-sourcing equipment installed.

Hardware Introduction

Supported Products

ModelSupported Products
F3Raspberry Pi 3B+, Raspberry Pi 4, ROCK Pi X, ROCK 3A, ROCK 3C, ROCK 4C+, Jetson Nano
F3LF3 with 40PIN GPIO pass-through exported
F4ROCK Pi 4A / 4B / 4A+ / 4B+ / 4SE
F4LF4 with 40PIN GPIO pass-through exported

The difference between F3 and F4 are:
F3 and F4 use different GPIO for fan control. F4 uses ADC for temperature detection, while F3 uses DS18B20.
F3 and F4 use different PoE pins. As the picture following:
Difference between F3 and F4

The difference between Fx and FxL:
FxL has the 40 pins GPIO pin-out, you can also use the 40 pins GPIO, but you can't while using Fx. As the picture following:
Fx and FxL
