 The Nano 33 BLE Sense adds an LPS22HB barometric pressure and temperature sensor, an HTS221 humidity sensor,
 an APDS-9960 digital proximity, ambient light, RGB, and gesture sensor,
 and an MP34DT05 digital microphone.
+The [Arduino Nano 33 BLE Sense Rev2](https://store-usa.arduino.cc/products/nano-33-ble-sense-rev2-with-headers)
+replaces the LSM9DS1 with a combination of the BMI270 and BMM150, the HTS221 with the HS3003, and the MP34DT05 with the MP34DT06JTR.
 
 Note: the Arduino Nano 33 BLE and BLE Sense do not include a QSPI external
 flash. Any Python code will need to be stored on the internal flash
