For the orange pi zero use this fork
https://github.com/nvl1109/orangepi_PC_gpio_pyH3
The original won't work.
That fork has the correct mappings for all of the pins. For a quick test try setting pins PA16 or PA15 and see if it works.
if you get
AttributeError: 'module' object has no attribute 'PA16'
then you've picked up the wrong module.
