New Nano 33 BLE Sense Rev2 board

Nano 33 BLE Sense Rev2 is a new Arduino board in a compact form factor with a set of sensors for machine learning and artificial intelligence in peripheral applications.

With the Nano 33 BLE Sense Rev2 in combination with the integrated sensor, you will be able to:
1. Create a wearable device that can recognize motion with AI.
2. Create a device to monitor room temperature.
3. Create a device to recognize gestures or voice using a microphone or gesture sensor along with AI capabilities.

The main feature of the Nano 33 BLE Sense Rev2 board is the ability to run Edge Computing (AI) applications using TinyML. Learn how to use the Tensor Flow Lite library by following the instructions, or train your board using the Edge Impulse web tool.
