A full, transistor-level schematic of the Raspberry Pi 5 (which isn’t publicly released), or
A block-level/doc-style “reference symbol” showing all of the Pi 5’s GPIO, power and bus pins so you can wire up your HAT.
Which of those were you looking for? If it’s the latter, we already have a “Raspberry Pi 2/3/4/5 Model B” connector symbol in your schematic—you can place and wire its header pins. Let me know which you need!
I couldn’t find any Flux documentation that lists the Raspberry Pi 5’s power rails and header pin numbers in a block-level connector symbol. It looks like that specific reference isn’t covered in Flux’s docs.
