Arduino Nano 33 BLE Sense Rev2
An AI enabled board in the shape of the classic Nano board, with all the sensors to start building your next project right away.
Overview
The Arduino Nano 33 BLE Sense Rev2 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.

Everyone in the world of smart and digital automation is getting ready to meet at SPS in Nuremberg. It’s the place to be if you want to see the future come to life – and of course a great opportunity to get to know Arduino better, with live demos and the chance to talk directly to our experts. Come visit booth 5-338 to discover our growing ecosystem of solutions and see it in action! “Since the 2022 edition of SPS, we’ve launched dozens of components, released software upgrades and added new services. But that’s only half the story. What we strive to achieve is to enable millions of Arduino users to imagine, implement and truly innovate. Our mission is to make technology accessible to all, to see people achieve the impossible. The maker philosophy may have started with tinkering in a messy garage, but has evolved into a distinct professional approach that allows everyone to seize the opportunities that come with the most disruptive phenomena of the present.”– Adriano Chinello, Pro Business Unit Leader at Arduino Without doubt, automation is one of the strongest trends we see today, with huge potential for future development. That’s why the applications we’ll showcase at SPS run the gamut from super-powerful edge computing to energy monitoring systems. For example, in Nuremberg you can check out how the Portenta X8 combines with the Portenta Max Carrier to deploy a secure, industrial-grade Linux computer – ready to interact with equipment in the factory or integrate with existing smart kiosks by creating a multi-protocol gateway that collects data from various onsite controllers, processes them and sends them to the Cloud via Wi-Fi, LoRa®, NB/IoT or LTE Cat.M1. Or you can find out how the Portenta Machine Control can be integrated in an electric panel to monitor consumption and other energy-related parameters... or team up with a Nicla Vision to control a robotic arm that automatically picks items from a conveyor belt and places
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.
