How many HATs can you put on a Raspberry Pi?

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.

Thereof, can you stack hats on a Raspberry Pi?

As Alex has said, HATS have to have an EEPROM that automatically configures them. That mechanism does not support stacking and will just fail if you try it.

Also, how do you stack hats? If you fold in the rear half of the cap toard the front, they will more easily stack, with visors facing forward. Stacking by color or season makes them more easily accessible. You can use a chain with clips on it and hang it behind a door or in the corner of a room. Hang each baseball cap on a clip.
