  • Just a comment about using this shield with an Arduino Mega: The Mega doesn’t support change interrupts on some of its pins, including pin 2 which is the pin this shield sends the RX to (in DLINE mode). So in order to get receiving data to work on a Mega, either use UART, or join pin 2 to one of the supported pins, and use that pin for RX. Supported pins: 10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69

  • In order to use a software UART with pins 2 & 3, don’t you need to short the pads on SJ1 and SJ3?? I don’t that mentioned anywhere.

    • It should work out of the box. We put a big ol' glob of solder across those jumpers during production to set them. You can kind of see them in this picture (bottom-right corner).

      • Ok, I feel better now, thought I was missing something.
