The Arduino Nano 33 BLE Sense Rev2 with headers is Arduino’s 3.3V AI enabled board in the smallest available form factor with a set of sensors that will allow you without any external hardware to start programming your next project, right away.
With the Arduino Nano 33 BLE Sense Rev2, you can:
- Build wearable devices that using AI can recognize movements.
- Build a room temperature monitoring device that can suggest or modify changes in the thermostat.
- Build a gesture or voice recognition device using the microphone or the gesture sensor together with the AI capabilities of the board.
The main feature of this board, besides the complete selection of sensors, is the possibility of running Edge Computing applications (AI) on it using TinyML. Learn how to use the Tensor Flow Lite library following this instructions or learn how to train your board using Edge Impulse.

FAQs
What is the difference between Rev1 and Rev2?
There has been some changes in the sensor between both revisions:
- Replacement of IMU from LSM9DS1 (9 axis) for a combination of two IMUs (BMI270 - 6 axis IMU and BMM150 - 3 axis IMU).
- Replacement of temperature and humidity sensor from HTS221 for HS3003.
- Replacement of microphone from MP34DT05 to MP34DT06JTR.
Additionally some components and the changes have been done in order to improve the experience of the users:
- Replacement of power supply MPM3610 for MP2322.
- Addition of VUSB soldering jumper on the top side of the board.
- New test point for USB, SWDIO and SWCLK.
Do I need to change my sketch used in the previous revision?
For sketches done using the libraries like LSM9DS1 for the IMU or HTS221 for the temperature and humidity sensor, for the new revision this libraries must be changed to Arduino_BMI270_BMM150 for the new combined IMU and Arduino_HS300x for the new temperature and humidity sensor.
