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 ATMEGA168P
Frequency 16MHz
Flash 15.50KB
Vendor Microchip


Please use ATMEGA168P ID for board option in “platformio.ini” (Project Configuration File):

platform = atmelavr
board = ATMEGA168P

You can override default ATMEGA168P/PA settings per build environment using board_*** option, where *** is a JSON object path from board manifest ATMEGA168P.json. For example, board_build.mcu, board_build.f_cpu, etc.

platform = atmelavr
board = ATMEGA168P

; change microcontroller
board_build.mcu = atmega168p

; change MCU frequency
board_build.f_cpu = 16000000L


PIO Unified Debugger currently does not support ATMEGA168P/PA 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.
