GPIO map for Orange Pi Zero Plus 2 (H3)

bitbank · Published in 2017-9-4 01:22:10

This board still has very little info available, so I manually mapped the GPIO ports through trial and error.

Each of the numbers below is the GPIO number used for /sys/class/gpio. For example, 110 means gpio110. The list is by pin number from 1 to 26. A value of -1 means unavailable (as far as I could discover):

-1, -1, 12, -1 (pin 1,2,3,4)

11,-1,6,0 (pin 5,6,7,8)

-1,1,352,107 (pin 9,10,11,12)

353,-1,3,19 (pin 13,14,15,16)

-1,18,-1,-1 (pin 17,18,19,20)

-1,2,14,13 (pin 21,22,23,24)

-1,110 (pin 25, 26)

I've added this table to my SPI_LCD project to make it easier to use for generic GPIO access without having know the details of working with the sysfs kernel driver: https://github.com/bitbank2/SPI_LCD

P.S. The red LED on the board is mapped to GPIO17
