Introduction

ROCK Pi PoE HAT is a HAT accessories designed for Raspberry Pi and ROCK Pi 4. The PoE HAT allows you to power your Raspberry Pi or ROCK Pi 4 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.

It comes with the following features:

802.3at up to 21W(5V/4.2A)
PWM control FAN up to 12000RPM
Temperature sensor DS18B20
Optional 40PIN GPIO pass-through exported
Compatible with ROCK Pi 4, Raspberry Pi 3B+ and Raspberry Pi 4
Clean design by hiding the fan and the big transformer inside
EEPROM for HAT identity and driver probe

Supplied with this product

ROCK Pi PoE HAT
Mechanical spacers

Other hardware needed

A Raspberry Pi 4 Model B or Raspberry Pi 3 Model B+ or ROCK Pi 4
An Ethernet cable
Power-sourcing equipment for a 802.3af Power over Ethernet network

Model

Model	Description
F3	Design for Raspberry Pi 3B+/4
F4	Use with ROCK Pi 4

The difference between F3 and F4 is, F3 and F4 uses different GPIO for fan control. F4 use ADC for temperature detection, while F3 uses DS18B20.
