Pololu A-Star 32U4

Hardware

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

Vendor

Pololu Corporation

Configuration

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

[env:a-star32U4]
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.

[env:a-star32U4]
platform = atmelavr
board = a-star32U4

; change microcontroller
board_build.mcu = atmega32u4

; change MCU frequency
board_build.f_cpu = 16000000L

Debugging

Debugging - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Pololu A-Star 32U4 does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.
