A pHat is Pi Zero sized, and a Hat is full sized.  
Pinout for Hats and pHats can be found here,  
[https://pinout.xyz/boards#](https://pinout.xyz/boards#)  
One way to combine them is with a pHat Stack, [https://shop.pimoroni.com/products/phat-stack](https://shop.pimoroni.com/products/phat-stack)  
or mini black hat hak3r, [https://shop.pimoroni.com/products/mini-black-hat-hack3r](https://shop.pimoroni.com/products/mini-black-hat-hack3r)  
This will tell you if one pHat or Hat conflicts with another.
