custom raspberry pi hat

Hello, I can design raspberry shield(hat) circuit and prepare its manufactering files. I use Eagle PCB software and it is free to download and use(till 80x100mm pcb and 2 layers). I would like to know that if you have schmatic file of the raspberry hat. I can send my designs over the chat for referances. All the BEST, Ali Serbetci
