Not only does the RPi foundation not release any board files for the RPi (fine, whatever), their "abbreviated schematic" is insultingly sparse [0]. The processor, memory, microSD card socket, Wi-Fi chip, USB hub chip, and Ethernet controller chip are all missing. If all you can get out of it is the pinout of the HAT and video connectors, then why did they even bother?
