I don't see anything that has been clear about which digital pins map to which physical ones. If someone could point me in the right direction it would be a big help.

For exampleThrough trial and error, i've found that if i set digital pin 3 in the Arduino IDE, it is mapped to D0 on J6, but surely this is documented somewhere?

    I just Google "Arduino Industrial 101", tab Images and found what you are looking for. Pinout for other Arduinos can be a good starting point, I guess
