Elektor Uno R4


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 ATMEGA328PB
Frequency 16MHz
Flash 31.50KB
Vendor Elektor


Please use elektor_uno_r4 ID for board option in “platformio.ini” (Project Configuration File):

platform = atmelavr
board = elektor_uno_r4

You can override default Elektor Uno R4 settings per build environment using board_*** option, where *** is a JSON object path from board manifest elektor_uno_r4.json. For example, board_build.mcu, board_build.f_cpu, etc.

platform = atmelavr
board = elektor_uno_r4

; change microcontroller
board_build.mcu = atmega328pb

; change MCU frequency
board_build.f_cpu = 16000000L


Debugging currently does not support Elektor Uno R4 board.
