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 ATTINY212
Frequency 16MHz
Flash 2KB
RAM 128B
Vendor Microchip


Please use ATtiny212 ID for board option in “platformio.ini” (Project Configuration File):

platform = atmelmegaavr
board = ATtiny212

You can override default ATtiny212 settings per build environment using board_*** option, where *** is a JSON object path from board manifest ATtiny212.json. For example, board_build.mcu, board_build.f_cpu, etc.

platform = atmelmegaavr
board = ATtiny212

; change microcontroller
board_build.mcu = attiny212

; change MCU frequency
board_build.f_cpu = 16000000L


Debugging currently does not support ATtiny212 board.
