Nano 33 BLE-board

Nano 33 BLE

The Arduino Nano 33 BLE shares its pinout with the classic Arduino Nano but builds on the nRF52840 microcontroller with 1MB CPU Flash Memory. Featuring a 9 axis inertial measurement unit and the possibility for Bluetooth® Low Energy connectivity it can help you to create your next Bluetooth® Low Energy enabled project.


The Arduino Nano 33 BLE is a great choice for any beginner, maker or professional to get started with Bluetooth® Low Energy enabled projects. It is build upon the nRF52840 microcontroller and runs on Arm® Mbed™ OS. The Nano 33 BLE not only features the possibility to connect via BLE but also comes equipped with a 9 axis IMU making it suitable for wearable projects.

u-blox NINA-B306

A powerful 2.4 GHz Bluetooth® 5 Low Energy module from u-blox, with an internal antenna.

IMU for Motion Detection

The LSM9DS1 inertial measurement unit features a 3D accelerometer, gyroscope and magnetometer and allows you to detect orientation, motion or vibrations in your project.

Arm® Mbed™ OS

Running on Arm® Mbed™ OS the Nano 33 BLE builds upon the same operating system as the Arduino Portenta H7. This also allows for Arduino APIs to be integrated using APIs exposed directly by Mbed OS.

Python Support

This board can be programmed with the Python programming language via the OpenMV IDE.

Lauterbach TRACE32 debugger

This board is compatible with Lauterbach TRACE32 debugger, and a free license can be obtained using the boards serial number.
