Yesterday, I tried to use the digital IO in my opi zero3, with the Python GPIO package from https://opi-gpio.readthedocs.io/en/latest/ by Richard Hull   It depends on having sysfs files in /sys/class/gpio/   My original opi zero has these files and it works, but my opi zero3 doesn’t have these files   I learned that /sys/class/gpio is created if the linux kernel is configured with a specific option ON, as suggested in the documentation: https://github.com/rm-hu
