• GPIO on Banana Pi: the RPi.GPIO and WiringPi ports only do simple I/O, and BCM numbers are translatedwarning · unverified · Banana Pi's docs point to ports of WiringPi (with gpio readall) and RPi.GPIO for boards like the BPI-M5, M2S, M4 Zero and F3. The RPi.GPIO port states that only simple I/O works — PWM, events and analog read are not implemented — apps need root, and BCM numbers are mapped to Banana Pi pins internally.
• GPIO on Orange Pi with wiringOP and wiringOP-Python: build it, read 'gpio readall', mind the three pin numberscode · unverified · wiringOP is Orange Pi's wiringPi port: build it from source, then 'gpio readall' prints each header pin with its Linux GPIO number, wiringPi number and physical pin. wiringOP-Python wraps it as the 'wiringpi' module. The numbers differ per board model, so always read them on your board.
