Stacking HATs

One of the cool things about this HAT design is that it is possible to stack them. Every HAT

you stack can control another 2 steppers or 4 DC motors (or a mix of the two)

You can stack up to 32 HAT for a total of 64 steppers or 128 DC motors! Most people will

probably just stack two or maybe three but hey, you never know. (PS if you drive 64

steppers from one Raspberry Pi send us a photo, OK?)

If you need to control a bunch of servos as well, you can use our 16-channel servo HAT and

stack it with this HAT to add a crazy large # of servos. (http://adafru.it/enA)

Stacking HATs is very easy. Each HAT you want to stack on top of must have stacking

headers installed. (http://adafru.it/2223) The top HAT does not have to have stacking

headers unless you eventually want to put something on top of it.
