Arduino Pro or Pro Mini ATmega328 (3.3V, 8 MHz)


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 8MHz
Flash 30KB
Vendor Arduino


Please use pro8MHzatmega328 ID for board option in “platformio.ini” (Project Configuration File):

platform = atmelavr
board = pro8MHzatmega328

You can override default Arduino Pro or Pro Mini ATmega328 (3.3V, 8 MHz) settings per build environment using board_*** option, where *** is a JSON object path from board manifest pro8MHzatmega328.json. For example, board_build.mcu, board_build.f_cpu, etc.

platform = atmelavr
board = pro8MHzatmega328

; change microcontroller
board_build.mcu = atmega328p

; change MCU frequency
board_build.f_cpu = 8000000L


PIO Unified Debugger currently does not support Arduino Pro or Pro Mini ATmega328 (3.3V, 8 MHz) board.


Name Description
Arduino Arduino Wiring-based Framework allows writing cross-platform software to control devices attached to a wide range of Arduino boards to create all kinds of creative coding, interactive objects, spaces or physical experiences.
