The documentation on the Orange Pi Zero Plus 2 is somewhat scarce. I couldn't find information on the GPIO map for the 26-pin header anywhere, but I manually mapped it. I did this with an LED on each successive pin and testing through the /sys/class/gpio driver until I found the one to control it. This caused a bunch of resets and eventually corrupted my sd card, but I got the info   Each of the numbers below is the GPIO number used for /sys/class/gpio. For example, 110 means gpio110.
