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 or 802.3at Power over Ethernet network
Software support
We provide a install script to help you get the PoE fan control tool that works both in Raspberry Pi 3B+/4B and ROCK Pi 4.
curl -sL https://rock.sh/get-rockpi-poe | sudo -E bash -
Just copy the command above and paste it into the terminal and press enter. If you want more control, check out section Fan Control at the bottom of the page.
Model
| Model | Description |
|---|---|
| F3 | Design for Raspberry Pi 3B+/4 |
| F3L | F3 with 40PIN GPIO pass-through exported |
| F4 | Use with ROCK Pi 4 |
| F4L | F4 with 40PIN GPIO pass-through exported |
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.

Fan Control
Turn the fan on or off by systemctl
sudo systemctl start rockpi-poe.service sudo systemctl stop rockpi-poe.service
Edit /etc/rockpi-poe.conf to set up temperature of the fan speed level, take it effect by below command
sudo systemctl restart rockpi-poe.service
