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.
