Atmel/Microchip ATmega328PB support for Arduino IDE

ATmega328PB Testing

Hardware

• Wattuino Pro Mini PB 5V 16MHz (with ATmega328PB)
• Wattuino Pro Mini PB 3.3V 8MHz (with ATmega328PB)

Software

Installation on Arduino IDE 1.8+

1. The Arduino AVR-GCC Toolchain (5.4.0-atmel3.6.0) supports the Atmega328PB. Further infos here.

2. Add the following URL to the Arduino Boards Manager (File->Preferences).

   https://github.com/watterott/ATmega328PB-Testing/raw/master/package_m328pb_index.json
   

3. Install the ATmega328PB Boards via the Boards Manager (Tools->Boards->Boards Manager).

Known Issues

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
