Overview
The Nano 33 BLE (without headers) is Arduino’s 3.3V compatible board in the smallest available form factor: 45x18mm!
The Arduino Nano 33 BLE is a completely new board on a well-known form factor. It comes with an embedded 9 axis inertial sensor what makes this board ideal for wearable devices, but also for a large range of scientific experiments in the need of short-distance wireless communication.
The Arduino Nano 33 BLE is an evolution of the traditional Arduino Nano, but featuring a lot more powerful processor, the nRF52840 from Nordic Semiconductors, a 32-bit ARM® Cortex®-M4 CPU running at 64 MHz. This will allow you to make larger programs than with the Arduino Uno (it has 1MB of program memory, 32 times bigger), and with a lot more variables (the RAM is 128 times bigger). The main processor includes other amazing features like Bluetooth® pairing via NFC and ultra low power consumption modes.
The Nano 33 BLE comes with a 9 axis inertial measurement unit (IMU) which means that it includes an accelerometer, a gyroscope, and a magnetometer with 3-axis resolution each. This makes the Nano 33 BLE the perfect choice for more advanced robotics experiments, exercise trackers, digital compasses, etc.
An Improved Arduino Nano
If you used Arduino Nano in your projects in the past, the Nano 33 BLE is a pin-equivalent substitute. Your code will still work, but remember, it operates at 3.3V. This means that you need to revise your original design in case it is not 3.3V compatible. Besides that, the main differences to the classic Nano are: a better processor, a micro-USB connector, and a 9 axis IMU.
You can get the board with or without headers, what will allow you embedding the Nano inside any kind of inventions, including wearables. The board comes with tessellated connectors and no components on the B-side. These features allow you to solder the board directly onto your own design, minimizing the height of your whole prototype.
Oh, and did we mention the improved price? Thanks to a revised manufacturing process, the Arduino Nano 33 BLE costs less than the original Nano … what are you waiting for? Upgrade now!
Bluetooth® and Bluetooth® Low Energy
The communications chipset on the Nano 33 BLE can be both a Bluetooth® Low Energy and Bluetooth® client and host device. Something pretty unique in the world of microcontroller platforms. If you want to see how easy it is to create a Bluetooth® central or a peripheral device, explore the examples at our ArduinoBLE library.

Learn to set up an Arduino Nano RP2040 Connect to use MicroPython.
Team Ikaro is a vibrant group of high school students from the Pacinotti Archimede Institute in Rome, sharing a strong passion for electronics and turning heads in the world of robotics! Specializing in Soccer Lightweight games (where robot-soccer players compete to score goals on a miniature field), they clinched the first place at the Romecup 2024 and won Italy’s national Robocup in Verbania earlier this year – earning the right to compete in the world championships in Eindhoven, where they placed third in the SuperTeam competition. The brains behind the bots Utilizing the versatile Arduino Nano RP2040 Connect, the team has crafted highly efficient robots that feature ultrasound sensors, PCB boards, a camera, four motors, a solenoid kicker and omni-directional wheels, all meticulously assembled in the school’s FabLab. Mentored by professor Paolo Torda, Team Ikaro exemplifies the spirit of innovation and teamwork bringing together three talented students: Francesco D’Angelo, the team leader, focuses on system design and mechanics; Flavio Crocicchia, the software developer, ensures the robots’ brains are as sharp as possible; Lorenzo Addario specializes in camera software, making sure the robots can “see” and react swiftly on the field. Their combined efforts have led to a seamless integration of hardware and software, and established a foundation of passion and ambition for future success in their careers. Future goals After their first taste of global competition, Team Ikaro is determined to continue refining their robots, leveraging every bit of knowledge and experience they gain – whether in the classroom, lab, or live challenges. At Arduino, we are proud to sponsor such brilliant young minds and look forward to seeing what they will accomplish next!
FAQs
Batteries, Pins and board LEDs
- Batteries: the Nano 33 BLE has no battery connector, nor charger. You can connect any external battery of your liking as long as you respect the voltage limits of the board.
- Vin: This pin can be used to power the board with a DC voltage source. If the power is fed through this pin, the USB power source is disconnected. This pin is an INPUT. Respect the voltage limits to assure the proper functionality of the board.
- 5V: This pin outputs 5V from the board when powered from the USB connector or from the VIN pin of the board. Note: for it to work, you need to short the VBUS jumper on the back of the board.
- 3.3V: This pin outputs 3.3V through the on-board voltage regulator. Note: for ultra low-power functionality, you should cut the 3V3 jumper on the back of the board, and use an external battery at 3V3.
- LED ON: This LED is connected to the 5V input from either USB or VIN.
- I2C pins: As opposed to other Arduino Nano boards, pins A4 and A5 have an internal pull up and default to be used as an I2C Bus so usage as analog inputs is not recommended.
- NFC: There is the possibility of attaching an external NFC antenna between pins D7 and D8 to emulate an NFC tag.
