I've recently bought a Triple GPIO Expansion Board in order to connect multiple sensors to my Raspberry pi while the number of open GPIOs (like model 3 B) are limited. This board has 4 sets of 40 GPIO pins and each column labeled as JP1 to JP4. I was wondering how can I set a specific pin while all look same with even the same pin number? In another word, How can I specify the pin for example 11 on the second column (JP2)? There should be a way to distinguish between each array of the board when defining the GPIO pin numbers in our code! for example:
I want to have a control on each GPIO separately in order to turn it on/off
LED_pin = 11 # @ JP1 Servo_IN1 = 11 # @ JP2
Thanks
