Interested in creating your own Pi HAT? I created a PCB layout template for KiCad and thought I would share it with the Pi community. It has the correct size outline, mounting holes for the Pi Zero or Pi 3, and correct placement of the GPIO connector. https://www.dropbox.com/s/i0olr0trd956k ... d_pcb?dl=0
