#189191 - good idea but
Responding to: Jan Waclawek's previous message
Seems a good idea, but my board is a multilayer and not easy to change. Although I can bend the POL pin and connect to GND. I'll try this later on this week

I also try 3.3V at Vcc

I'm awaiting further response from Atmel the coming hours.

Thx
