unascribed's GPIO Pinout Diagrams

These are just raw pin offsets, for those who already know what they need and are working with non-Raspberry or old Raspberry SBCs. I highly recommend pinout.xyz if you want to know the standard uses of certain pins, or check HATs and such. The design of these diagrams is inspired by (a now former version of) pinout.xyz.

Please send me an email (me@unascribed.com) if you have a board you'd like added here. Please link a schematic or wiki page to use as the basis for the information. (Note I can only personally decipher Rockchip and Allwinner GPIO pin name conventions; schematics for other SoCs will likely be illegible to me.)

Syntax: gpiochip:offset. For example, 1:4 means /dev/gpiochip1 offset 4. The diagrams are designed to have "landmarks" on them to provide orientation. Generally, these landmarks come in the form of mounting holes, but for some boards it may be e.g. dedicated debug UART headers. Hold up your board to the screen and rotate it until it makes sense. The aspect ratio of the boards may at times be exaggerated, and most diagrams only show a portion of the board, but there should be one and only one "logical" orientation. If you're confused, send me an email.

The Raspberry Pi A+/B+, NanoPi M4, and Banana Pi M2 Zero pinouts are known-good as I've used them myself. Other boards have been compiled from external information sources, sometimes requiring quite a bit of digging in the case of the Rev1 Raspberry Pi and the Model A/B's P5 header. Please use the information provided here with caution (especially if you intend to provide 5v via a GPIO header; connecting 5v to a 3v GPIO is a good way to kill your board) and report any inaccuracies to my email.
