Hi, I just bought a Raspberry Pi zero and I’m fairly new to all this. I want to use a capacitive touch interface to control three servos, independent of one another.
For the touch input, I am looking at purchasing either the Touch phat (https://shop.pimoroni.com/products/touch-phat) or the drum hat (https://shop.pimoroni.com/collections/raspberry-pi/products/drum-hat).
The problem is, I can’t figure out how I would use either of these hats and still be able to have room for the servos. The hats seem to cover the GPIOs. How would I get around this and make room for some sort of PWM controller or anything else that lets me control three servos? Could you link to what servo controllers would work for this application, and explain how they would connect when there is already a hat on the pi?
