The Nanopi Fire3 - GPIO

See chapter 16 in the S5P6818 user manual. In theory at least, there are 160 pins available for GPIO.

There are 5 gpio units, each with 32 bits. These are designated A, B, C, D, E. The base address is 0xC001x000, where "x" is A, B, C, D, or E.

The 40 pin connector

This provides 40 pins that are more or less compatible with the 40 pin Raspberry Pi connector. Power and ground are on the expected pins. The other pins are controlled by some kind of GPIO - and that is what the compatibility seems to boil down to. I don't particularly care as I don't in any way expect this to be plug compatible with a Raspberry Pi.
