SparkFun Mega Pro Mini 3.3V¶

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

Configuration¶

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

[env:sparkfun_megamini]
platform = atmelavr
board = sparkfun_megamini

You can override default SparkFun Mega Pro Mini 3.3V settings per build environment using board_*** option, where *** is a JSON object path from board manifest sparkfun_megamini.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:sparkfun_megamini]
platform = atmelavr
board = sparkfun_megamini

; change microcontroller
board_build.mcu = atmega2560

; change MCU frequency
board_build.f_cpu = 8000000L

Debugging¶

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

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

SparkFun Mega Pro Mini 3.3V has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
