Those new images I sent should be more forgiving with the protocol but I 
haven't dropped OpenWRT on the Pi3 yet to try it there.

I am going to add code to use a PWM to adjust the big red LED brightness as a 
precursor to using one in an EMC lab for an IEEE site visit.

I may put a long wire on the LED on one of the units too so it radiates more 
and gives us something interesting to look at.

We will do an immunity test with the human discharge probe to see if it 
survives. it is typically a destructive test and I am thinking the board may 
need one more component; a two circuit TVS designed to stop the discharge 
going into the USB port. The nasty test will tell us if is needed.

It is turning out to be a useful board to do various things. If I have to 
re-spin the board I will try to make it accept standard USB and USB-C 
connectors also.

All the best
Harry
