Arduino Nano 33 Sense Rev2
What is Arduino Nano 33 Sense Rev2?
The Arduino Nano 33 BLE Sense Rev2 (often called Nano 33 Sense Rev2) is a compact, low-power IoT and sensor-rich development board designed for machine learning, audio processing, motion detection, and environmental sensing.
It’s the successor to the original Nano 33 BLE Sense, improving performance, accuracy, and sensor reliability. Know more.

Library Changes from Rev1 to Rev2
| Sensor Type | Rev1 Library | Rev2 Library |
|---|---|---|
| IMU (9-axis) | LSM9DS1 | Arduino_BMI270_BMM150 |
| Temperature & Humidity | Arduino_HTS221 | Arduino_HS300x |
| Microphone (PDM) | MP34DT05 (generic PDM library) | MP34DT06JTR (same PDM interface) |
Code Update
If you have developed code for rev1, some of them will need to be modified for rev2, especially the ones that involve the IMU sensor and the Temperature & Humidity sensor.
