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

platform = atmelsam
board = sainSmartDueUSB

You can override default SainSmart Due (USB Native Port) settings per build environment using board_*** option, where *** is a JSON object path from board manifest sainSmartDueUSB.json. For example, board_build.mcu, board_build.f_cpu, etc.

platform = atmelsam
board = sainSmartDueUSB

; change microcontroller
board_build.mcu = at91sam3x8e

; change MCU frequency
board_build.f_cpu = 84000000L


SainSmart Due (USB Native Port) supports the next uploading protocols:

  • atmel-ice
  • blackmagic
  • jlink
  • sam-ba
  • stlink

Default protocol is sam-ba

You can change upload protocol using upload_protocol option:

platform = atmelsam
board = sainSmartDueUSB

upload_protocol = sam-ba


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


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).

SainSmart Due (USB Native Port) 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.
