Arduino Nano 33 BLE Sense Rev2 with headers
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 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.

A simple BlueTooth (BLE) remote controller for the Arduino Alvik robot, implemented in MicroPyhton
We’re thrilled to announce that Arduino Education has been shortlisted for the Bett Awards 2025, this time in the AV, VR/AR, Robotics, or Digital Device category with our Alvik robot! This recognition highlights our dedication to innovation, inclusivity, and the advancement of practical STEM education. The Bett Awards celebrate leading-edge technology in education, with entries evaluated on key criteria such as innovation, curriculum suitability, online safety, research evidence, customer support and more. About the Alvik robot Alvik is an adaptable, lifelong learning robot that supports educators and students as they transition from block-based programming to text-based coding using MicroPython and Arduino language. It enables them to explore robotics and tackle real-life challenges with comprehensive learning content. However, Alvik isn’t just designed to teach programming and robotics; it can also enhance students’ understanding of topics like mathematics and astronomy, along with other engaging projects. Alvik’s curriculum-aligned course makes it an ideal fit for today’s classrooms, empowering students with hands-on skills and a strong foundation in STEAM. But what truly sets Alvik apart from other educational robots is its limitless potential for customization. Students and teachers can easily add external sensors using the I2C Grove and Qwiic plug-and-play connectors, eliminating the need for soldering or complex wiring. Additionally, the LEGO® Technic™ and M3 screw connectors encourage hands-on creativity, allowing users to build custom components and further expand Alvik’s capabilities. We’re honored to be recognized once again, and we can’t wait to attend Bett in just a couple of months. The winners will be announced at the Bett Awards 2025 Ceremony on January 22nd at The Brewery, London. We look forward to seeing you there!
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.
