Arduino Uno


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 31.50KB
Vendor Arduino


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

platform = atmelavr
board = uno

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

platform = atmelavr
board = uno

; change microcontroller
board_build.mcu = atmega328p

; change MCU frequency
board_build.f_cpu = 16000000L


PIO Unified Debugger currently does not support Arduino Uno 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.
Simba Simba is an RTOS and build framework. It aims to make embedded programming easy and portable.
