#189191 - good idea but Responding to: ???'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 |
