QUESTIONS & ANSWERSAsk a Question
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?

Second hat with fan cooling from yahboom. With the first hat The fan stopped about 3 month. But very easy to install and program with python. The oled display is perfect to see the IP of the raspi.
This expansion board is good overall, it can not only cooling, but also display the current temperature, CPU, and IP address of the Raspberry Pi in real time.
But the green breathing light, which is activated by default, really disgusts me, so I only have to give it 3 star.
This product is amazing and suitable and the best of all, it has its own mini OLED!! Best features for my Basiliscus Basilisk mandalorian :) keep doing it!
Provided SW is not usable so I implemented the daemon which controls the HW. See https://github.com/vookimedlo/yahboom_RGB_Cooling_HAT if you are interested in.
Had to piece together all the software, the manual and guide uses outdated drivers and python code provided is not very good. Builiding my own python software that works on the hat was a long and difficult process (I had little experience with i2c). That said, the Hat hardware is very cool overall and im sure experienced programmers would have no difficulty writing their own python code to use.
