Perhaps it's a shield issue? Have you tried checking the pin headers for correct volt/ground without the nano installed?
Hi tinman13kup,
I assume every row labeled with G and V should deliver 5 V or which pins should deliver 5V. I also see some pins labeled with 3V3 which should deliver 3.3V against ground. Right ?
I just measured all pins and all the rows labeled with V and G deliver around 150mV. The ones labeled with 5V and 3V3 do not deliver anything.
The only pins which deliver voltage are Vin and GND which connect to the NANO.
So I guess this board was defective ... Another experience with a total cost of US $ 7.50 
Thanks and regards Rainer
