Please use briki_abc_samd21 ID for board option in “platformio.ini” (Project Configuration File):

platform = atmelsam
board = briki_abc_samd21

You can override default Briki ABC (MBC-WB) - Samd21 settings per build environment using board_*** option, where *** is a JSON object path from board manifest briki_abc_samd21.json. For example, board_build.mcu, board_build.f_cpu, etc.

platform = atmelsam
board = briki_abc_samd21

; change microcontroller
board_build.mcu = samd21g18a

; change MCU frequency
board_build.f_cpu = 48000000L


Briki ABC (MBC-WB) - Samd21 supports the next uploading protocols:

  • atmel-ice
  • blackmagic
  • jlink
  • mbctool
  • sam-ba
  • stk500v2

Default protocol is mbctool

You can change upload protocol using upload_protocol option:

platform = atmelsam
board = briki_abc_samd21

upload_protocol = mbctool


Debugging - “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).

Briki ABC (MBC-WB) - Samd21 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.

Compatible Tools On-board Default
Atmel-ICE   Yes
