Replying to myself I was able to to program flashing LED code into the RedBoard via ArduinoDroid. In settings I select Uno, but there is an error about unrecognized board when trying to upload, so I choose Pro/328/5v option since Uno isn’t in this list. It uploaded quickly (under 10sec I think), and the LED started flashing per my code.
My next issue to work through… I am not seeing any print messages in the ArduinoDroid output tab.
