Arduino Nano 33 BLE SENSE rev2 Microcontroller - Arduino

The Arduino Nano 33 BLE Sense Rev2 is a 3.3V Arduino board prepared for Artificial Intelligence algorithms and has the smallest format available.

Despite its small size, this board has a vast set of sensors that will allow you, without any external hardware, to start programming your next project immediately.

With the Arduino Nano 33 BLE Sense Rev2, you can:
◾ Build wearable devices that, using AI, can recognize movements or gestures.
◾ Build a room temperature monitoring device that can suggest or modify changes to a thermostat.
◾ Build a voice recognition device using the included microphone.

The main feature of this board, in addition to the complete selection of sensors, is the possibility of running Artificial Intelligence applications, using TinyML.
