Pololu A-Star 32U4


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 ATMEGA32U4
Frequency 16MHz
Flash 28KB
RAM 2.50KB
Vendor Pololu Corporation


Please use a-star32U4 ID for board option in “platformio.ini” (Project Configuration File):

platform = atmelavr
board = a-star32U4

You can override default Pololu A-Star 32U4 settings per build environment using board_*** option, where *** is a JSON object path from board manifest a-star32U4.json. For example, board_build.mcu, board_build.f_cpu, etc.

platform = atmelavr
board = a-star32U4

; change microcontroller
board_build.mcu = atmega32u4

; change MCU frequency
board_build.f_cpu = 16000000L


PIO Unified Debugger currently does not support Pololu A-Star 32U4 board.
