Arduino Nano 33 BLE Sense Description

The Nano 33 BLE Sense (with headers) is Arduino's 3.3V AI board in the smallest available form factor: 45x18mm! The Arduino Nano 33 BLE Sense is a completely new board with a familiar form factor. It comes with a range of built-in sensors:

• 9-axis inertial sensor: what makes this board ideal for wearable devices
• humidity and temperature sensor: for highly accurate measurements of environmental conditions
• barometric sensor: you could make a simple weather station
• microphone: to capture and analyze sound in real time
• gesture, proximity, light color and light intensity sensor: estimates the brightness of the room, but also whether someone is moving near the board

The Arduino Nano 33 BLE Sense is an evolution of the traditional Arduino Nano, but with a much more powerful processor, the nRF52840 from Nordic Semiconductors and a 32-bit ARM® Cortex™ -M4 CPU with 64 MHz. This allows you to create larger programs than with the Arduino Uno . The main processor includes other amazing features such as Bluetooth® pairing via NFC and very low power consumption.

The main feature of this board, besides the impressive selection of sensors, is the ability to run Edge Computing (AI) applications on it using TinyML. You can create your machine learning models with TensorFlow™ Lite and upload them to your board using the Arduino IDE.

The communication chipset on the Nano 33 BLE can be both a BLE and Bluetooth® client and host device. Something quite unique in the world of microcontroller platforms. If you want to see how easy it is to create a Bluetooth® central or peripheral device, check out the examples in our ArduinoBLE library .

If you have used Arduino Nano in your projects in the past, Nano 33 BLE is a pin-equivalent alternative. Your code will still work, but remember that it works at 3.3V. This means you will have to rethink the original design in case it is not 3.3V compatible. Other than that, the main differences from the classic Nano are: a better processor, a micro USB connector and a 9-axis IMU.
