ATmega328PB Discussion in the Italian Arduino Forum: http://forum.arduino.cc/index.php?topic=374642.0
ATmega328P and ATmega328PB have different thresholds for reset. This can be a problem when using a 5V power supply for the microcontroller and an USB serial adapter with 3.3V logic level on DTR.
- Reset Input Threshold Voltage (read as 0/low):
- ATmega328P: 2.1V @ Vcc=5V
- ATmega328PB: 1.6V @ Vcc=5V
- Patch v1.0.1 - Astrobeed, gpb01, PaoloP
- avr-gcc 4.9.2 for linux64 - sabas1080
