Introduction

Rockpi with poe hat.png

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

Manual installation

If you have trouble installing software using our script, try manual installation.

1. Enable hardware resources

For speed control and temperature detection, we need to ensure that some hardware resources are available, such as PWM and ADC. Since ROCK Pi and Raspberry Pi use different resources, they will be explained below.

1.1 ROCK Pi

If you are using the official system, please edit /boot/hw_intfc.conf to change intfc:pwm0=off and intfc:pwm1=off into intfc:pwm0=on and intfc:pwm1=on. If you are using other system, please refer to the distribution documentation to open PWM0 and PWM1.

1.2 Raspberry Pi

If you are using Raspbian, you can open 1-Wire with raspi-config and the path is Interfacing Options -> 1-Wire. Raspbian turns on PWM1 by default. If you are using other system, please refer to the distribution documentation to open 1-Wire and PWM1.

2. Install GPIO control library

2.1 ROCKP Pi

If you are using the official system, please install libmraa-rockpi4 from testing repo of Radxa APT. If you are using other system, please download mraa and build.

2.2 ROCKP Pi

If you are using Raspbian, you can install python3-rpi.gpio via apt. If you are using other system, please download raspberry-gpio-python and build.

3. Download package and install

3.1 ROCK Pi

   wget https://cos.setq.me/rockpi-deb/rockpi-poe-0.13.deb

If you are using a debian based system, you can install it through dpkg. If you are using other system, extract the file to the root directory.

3.2 Raspberry Pi

   wget https://cos.setq.me/rockpi-deb/raspi-poe-0.13.deb

If you are using a debian based system, you can install it through dpkg. If you are using other system, extract the file to the root directory.

4. Enable service

   sudo systemctl enable rockpi-poe.service

That's all the installation script (https://rock.sh/get-rockpi-poe) do.
