[werk_ag]

I'm starting to wonder whether the DCCduino Nano (cheap clone) on the Rx board may be faulty. Maybe it could be faulty around the switching circuitry that Werk_AG outlined. I am just in the process of purchasing a genuine Arduino Nano, to see if that will make a difference.

GreggWardNZ, I never used a DCDuino Nano version, but I always used cheap chinese Nano clones, and generally they work well.

If you gonna try with another arduino, try a different model of the DCDuino. These are really good (Can't assure the FTDI chip is original, but vendors claims it is)





What I like more is these models are the voltage regulator, seems more capable for high currents than the AMS1117 installed on other Nano's. The N00A regulator is a LM340 in a SOT-233 package
