+The Nano 33 BLE Sense Rev2 adds an LPS22HB barometric pressure and temperature sensor, an HS3003 humidity sensor,
+an APDS-9960 digital proximity, ambient light, RGB, and gesture sensor,
+and an MP34DT06JTR digital microphone.
+
+Note: the Arduino Nano 33 BLE Rev2 and BLE Sense Rev2 do not include a QSPI external
+flash. Any Python code will need to be stored on the internal flash
+filesystem.
