+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.

+
+Pins `board.LED_G` and `board.LED_Y` are onboard green and red LEDs. `board.LED_Y` is also `board.SCK`.
