Description
The Arduino Nano 33 BLE Sense Rev2 with headers is Arduino’s 3.3 V 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.
Differences between Rev1 and Rev2
- Replacement of IMU from LSM9DS1 (9 axis) for a combination of two IMUs (BMI270 – 6 axis IMU and BMM150 – 3 axis IMU)
- Replacement of temperature and humidity sensor from HTS221 for HS3003
- Replacement of microphone from MP34DT05 to MP34DT06JTR
- Replacement of power supply MPM3610 for MP2322
- Addition of VUSB soldering jumper on the top side of the board
- New test point for USB, SWDIO and SWCLK
