Can Raspberry Pi HATs be stacked?

Even though HATs are not intended to be stacked, you can stack up to 62 HATs and not have an address collision, for up to 992 PWM outputs! You’ll still need to provide power and write code for all those outputs but they can all share the same SDA/SCL pins no problem.

Can you use multiple HATs on Raspberry Pi?

There are multiple HATs that one can connect with the Raspberry Pi that not only makes the device powerful but also makes the user faster. One can enhance the effect of a HAT by connecting the 3 HAT with the Raspberry Pi.
