Arduino Duemilanove or Diecimila ATmega328


Platform Atmel AVR: Atmel AVR 8- and 32-bit MCUs deliver a unique combination of performance, power efficiency and design flexibility. Optimized to speed time to market-and easily adapt to new ones-they are based on the industrys most code-efficient architecture for C and assembly programming.

Microcontroller ATMEGA328P
Frequency 16MHz
Flash 30KB
Vendor Arduino


Please use diecimilaatmega328 ID for board option in “platformio.ini” (Project Configuration File):

platform = atmelavr
board = diecimilaatmega328

You can override default Arduino Duemilanove or Diecimila ATmega328 settings per build environment using board_*** option, where *** is a JSON object path from board manifest diecimilaatmega328.json. For example, board_build.mcu, board_build.f_cpu, etc.

platform = atmelavr
board = diecimilaatmega328

; change microcontroller
board_build.mcu = atmega328p

; change MCU frequency
board_build.f_cpu = 16000000L


PIO Unified Debugger currently does not support Arduino Duemilanove or Diecimila ATmega328 board.
