Lots of folks have been wanting support for the Arduino Nano 33 BLE Sense Rev2, as the original Rev1 has been notoriously difficult to obtain. This has been due to a shortage of a few parts required to build the board. I’m happy to announce that the Rev2 is now officially supported! See the updated Arduino Nano 33 BLE Sense guide for more information.
Note that when you examine the examples from a deployed Arduino library, you will see only accelerometer and fusion samples for the Rev2. That’s because the IMU and temperature/humidity sensors are different between the Rev1 and Rev2.
You should use the camera and microphone examples from the nano_ble33_sense category for the Rev1 and Rev2, as those sensors are the same between the boards.
