If you are looking for the product with soldered header than,
The Nano 33 BLE Sense with headers comes with the soldered header. It is Arduino’s 3.3V AI enabled board in the tiniest available form factor i.e. 45x18 mm! The Arduino Nano 33 BLE Sense is a completely new board on a well-known form factor. It comes with a series of embedded sensors:
1. 9 axis inertial sensor: what makes this board ideal for wearable devices
2. Humidity, and temperature sensor: to get highly accurate measurements of the environmental conditions.
3. Barometric sensor: you could make a simple weather station
4. Microphone: to capture and analyse sound in real time
5. Gesture, proximity, light colour and light intensity sensor: estimate the room’s luminosity, but also whether someone is moving close to the board.
