Too much work to setup

I did not realize the amount of time and effort to find and install all the support, fine for your products that already had one. Not good for others.

This radiator is very good, it's exactly what I want.
At present, it is working normally.

Image file deleted from internet! Virus maybe?

They used to have a .img file provided on their website but it was taken down. Maybe the customers informed them that malware or viruses were on the image file. Not recommended.

Been loving it for a few years

I bought this HAT a few years ago on Amazon.com and love it. I enjoy the multiple functions and the python code has been a lot of fun to experiment with!
In addition to the Pi 4 and 3 advertised, it also works on the older 2 and 1. I use mine on a Pi 1B+ web server and over time have modified the code to set the RGB lighting to a single color, changed the text displayed on the LED, and added an input monitors to handle a piezo buzzer and GPIO matrix keypad.
Last year the LED was showing bad burn-in making the text unreadable and I replaced it with a larger 64x128 that uses the same SSD1306 chipset and, therefore, no code modifications had to be made. Although I did make one small modification to blank the display once in a while to hopefully reduce the risk of future burn-in.
The fan has also been noisy and stuttery for a while and I am looking into the possibility of replacing it...

Good service, product not perfect

I am satisfied with this cooling fan as a whole, but I encountered some problems when setting the RGB lighting. The technical customer service communicated with me in real time on WhatsApp. Although his English is very bad, he finally helped us solve the problem.
If you're using the latest Raspberry Pi 8G board, it sometimes doesn't work.

  • I recently bought your Pi cooling had and it seems that the code that is on github uses deprecated libraries that are making it hard for the hat to work. Is there ever going to be updated code?
