Pixhawk 6C reference design/schematics

Hi, I’m playing around with writing my own firmware for my Holybro Pixhawk 6C and am running into a few issues getting some of the IO working. I’m wondering if the design spec or schematics are available for the FMUv6 as most of the documentation pages I’ve found look like they haven’t been updated since the FMUv5. Thanks.
