## Hardware

Platform Atmel megaAVR: 8-bit MCUs Built for Real-time Control with Core Independent Peripherals combining intelligent hardware peripherals along with the low-power capability of an AVR core, megaAVR microcontrollers (MCUs) broaden the effectiveness of your real-time control systems.

Microcontroller | ATMEGA4809
Frequency | 16MHz
Flash | 47.50KB
RAM | 6KB
Vendor | Arduino

## Configuration

Please use `uno_wifi_rev2` ID for board option in “platformio.ini” (Project Configuration File):

    [env:uno_wifi_rev2]
    platform = atmelmegaavr
    board = uno_wifi_rev2

You can override default Arduino Uno WiFi Rev2 settings per build environment using `board_***` option, where `***` is a JSON object path from board manifest uno_wifi_rev2.json. For example, `board_build.mcu`, `board_build.f_cpu`, etc.

    [env:uno_wifi_rev2]
    platform = atmelmegaavr
    board = uno_wifi_rev2

    ; change microcontroller
    board_build.mcu = atmega4809

    ; change MCU frequency
    board_build.f_cpu = 16000000L

## Debugging

PIO Unified Debugger currently does not support Arduino Uno WiFi Rev2 board.

## Frameworks
