Raspberry Pi RGB Cooling HAT with adjustable fan and OLED display for Pi5/4B/3B+/3B

Raspberry-Pi-RGB-Cooling-HAT

Introduction

This is a Multi-function cooling expansion board designed for the Raspberry Pi board. It is perfectly compatible with the Pi5/4B/3B+/3B to protect Raspberry Pi and extends its life. A 4pin IIC interface for OLED display, which can real-time display CPU temperature, CPU usage, hard disk space, memory and IP address. The large-size cooling fan on the board with strong wind power, it can make Raspberry Pi can run more stably by automatically adjust the speed according to the CPU temperature. 3 high-brightness RGB programming lights on the bottom of the expansion board, which can realize following lights, breathing lights, marquees and so on. It also expandS Raspberry Pi 40pin header and can be used to connect to other devices. We will provide a driver package for all Raspberry Pi images, which is convenient for users to drive fans, OLED displays, RGB lights.

Features

• Perfectly compatible with Raspberry Pi 5/4B/3B+/3B, not occupy any Raspberry Pi pin, not occupy heat sink space.

• The powerful fan on the board can automatically adjust the speed according to the CPU temperature to control the air volume.

• Support OLED display, which can display the running status of Raspberry Pi in real-time.

• High-brightness RGB lights to enhance the aesthetic appearance, but also to achieve a variety of funny lighting gameplay.

• Users can use C language programming and Python programming.

• A driver package that can drive all the functions of the expansion board, as well as program source code and tutorials will be provided.

incompatibility with module ATXRaspi

Guys,
I'm not able to use the ATXRaspi module together with RGB Cooling HAT(Yahboom_image)

Scrip Install do module ATXRaspi
https://raw.githubusercontent.com/LowPowerLab/ATX-Raspi/master/shutdownchecksetup.sh
sudo bash shutdownchecksetup.sh
sudo rm shutdownchecksetup.sh
sudo reboot

License?

Hi,

Would it be possible to add a LICENSE file to this project? I'd like to use some of the code in my own project but I'm not sure what the rights are.

Full feature solution

If anybody is interested in the full feature solution which can be also executed as a daemon, here is the solution I implemented - https://github.com/vookimedlo/yahboom_RGB_Cooling_HAT

How to turn default green light off?

Hello. What should I edit in C-code in order to turn default green light off? I don't need any interfering lights.

RGB control

What the heck is wrong with the RGB control?

Using the supplied rgb.py script, it turns on random LEDs to random colors every time I run it.

The last line of the script is:

setRGB(Max_LED, 0, 0, 255)

As I read it, Max_LED sets all 3 lights, no red or green, and 100% blue - so this line says turn all 3 lights blue (0,0,255)....but that isn't what happens. I may or may not get all 3 lights, the lights that do turn on may or may not be blue. It seems completely random.

When I write a script to control a single LED, turning LED0 white (255,255,255) - it's a toss up as to which LED comes on, and what color it is when it does.

import smbus
import time
bus = smbus.SMBus(1)

addr = 0x0d
rgb_off_reg = 0x07

def setRGB0(r, g, b):
    bus.write_byte_data(addr, rgb_off_reg, 0x00)
    #time.sleep(2)
    bus.write_byte_data(addr, 0x00, 0&0xff)
    bus.write_byte_data(addr, 0x01, r&0xff)
    bus.write_byte_data(addr, 0x02, g&0xff)
    bus.write_byte_data(addr, 0x03, b&0xff)

setRGB0(255,255,255)
