The Arduino Nano 33 BLE Sense Rev2 with headers is Arduino's 3.3 V AI-capable board in the smallest available form factor. It features a range of sensors that allow you to start programming your next project immediately without the need for external hardware.

With the Arduino Nano 33 BLE Sense Rev2, you can:

• Build wearable devices that can recognise movements using AI.
• Create a device to monitor room temperature that can suggest or make changes to the thermostat.
• Develop a device for gesture or voice recognition that utilises the microphone or gesture sensor alongside the board's AI capabilities.

The main feature of this board, in addition to the wide selection of sensors, is the ability to run edge computing applications (AI) with TinyML. Learn how to use the TensorFlow Lite library by following the instructions, or discover how to train your board with Edge Impulse.
