Generic ATtiny43U


Platform Atmel AVR: Atmel AVR 8-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 industry’s most code-efficient architecture for C and assembly programming

Microcontroller ATTINY43U
Frequency 8MHz
Flash 4KB
RAM 256B
Vendor Atmel


Please use attiny43 ID for board option in “platformio.ini” (Project Configuration File):

platform = atmelavr
board = attiny43

You can override default Generic ATtiny43U settings per build environment using board_*** option, where *** is a JSON object path from board manifest attiny43.json. For example, board_build.mcu, board_build.f_cpu, etc.

platform = atmelavr
board = attiny43

; change microcontroller
board_build.mcu = attiny43u

; change MCU frequency
board_build.f_cpu = 8000000L


Debugging currently does not support Generic ATtiny43U board.
