• Looking here https://forum.wemos.cc/topic/8/d1-to-ard­uino-uno-pinout-associations/2

    The pinouts are no clearer!

    I would try all the combinations - D5, nodemcu:D5 and work your way through the range.

    You can paste in the left side of the ide, and press the button and see if you have output - if not use the up arrow and then back arrow and change to D6, and hit return. Very quickly you can go through the whole range...

  • It doesn't matter which assignment I use...at least I now know I have the R2 version of the board.

    Also I now can use the Block Based IDE using the pins from that diagram.
