Arduino Nano 33 BLE

Hardware

Platform Nordic nRF52: The nRF52 Series are built for speed to carry out increasingly complex tasks in the shortest possible time and return to sleep, conserving precious battery power. They have a Cortex-M4F processor and are the most capable Bluetooth Smart SoCs on the market.

Microcontroller NRF52840
Frequency 64MHz
Flash 960KB
RAM 256KB
Vendor Arduino

Configuration

Please use nano33ble ID for board option in “platformio.ini” (Project Configuration File):

[env:nano33ble]
platform = nordicnrf52
board = nano33ble

You can override default Arduino Nano 33 BLE settings per build environment using board_*** option, where *** is a JSON object path from board manifest nano33ble.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:nano33ble]
platform = nordicnrf52
board = nano33ble

; change microcontroller
board_build.mcu = nrf52840

; change MCU frequency
board_build.f_cpu = 64000000L

Uploading

Arduino Nano 33 BLE supports the next uploading protocols:

  • blackmagic
  • cmsis-dap
  • jlink
  • nrfjprog
  • nrfutil
  • sam-ba

Default protocol is sam-ba

You can change upload protocol using upload_protocol option:

[env:nano33ble]
platform = nordicnrf52
board = nano33ble

upload_protocol = sam-ba

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).

Arduino Nano 33 BLE 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
Black Magic Probe   Yes
CMSIS-DAP    
J-LINK    

Frameworks
