Review on Enhance Your Raspberry Pi 4B Performance: Cooling Fan, RGB Hat, and OLED Display Combo! by Lisa Varela

I'm not an experienced programmer and I'm struggling with it. I can usually follow instructions and copy/paste commands, but I feel the instructions should be revised to be much easier. This fan HAT has many features and it seems like the instructions for each individual feature have been duplicated. Most people will use all of the features in one way or another. An easy one stop download with easy links to change setpoints for fans, LED color etc. would make this a great product. . The little display that plugs in from the top was a great concept for monitoring CPU temperatures etc, but the readings on my screen didn't match what the Raspberry Pi was reporting directly. I'm sure this could have been calibrated differently to be more accurate, but that's outside the scope of what I was trying to find out. That being said, there are a lot of really nice features if you can get it working: - The large fan is very quiet and can cool very efficiently. I prefer a large fan like this over other options with smaller fans. - Using PWM to adjust fan speed based on CPU temperature is a great feature. - The ability to change the color of the LED to show the CPU temperature is also very cool. .- The pass-through slot for the camera ribbon cable is essential for my work. This is not available on all boards. All GPIO pins are available. Some HAT fans use two GPIO pins so you can't use a parallel cable, but they're all available. and I just leave it on when my Pi is running.
