# Arduino Nano 33 BLE Rev2 and Nano 33 BLE Sense Rev2
2
+
3
+
The [Arduino Nano 33 BLE Rev2](https://store.arduino.cc/usa/nano-33-ble-rev2) and
4
+
[Arduino Nano 33 BLE Sense Rev2](https://store.arduino.cc/usa/nano-33-ble-sense-rev2)
5
+
are built around the NINA-B306 module, based on the Nordic nRF52840 and containing
6
+
a powerful Cortex-M4F. Both include an onboard 9-axis Inertial Measurement Unit (IMU), made up of the BMI270 6-axis IMU and the BMM150 3-axis magnetometer.
7
+
The Nano 33 BLE Sense Rev2 adds an LPS22HB barometric pressure and temperature sensor, an HS3003 humidity sensor,
8
+
an APDS-9960 digital proximity, ambient light, RGB, and gesture sensor,
9
+
and an MP34DT06JTR digital microphone.
10
+
11
+
Note: the Arduino Nano 33 BLE Rev2 and BLE Sense Rev2 do not include a QSPI external
12
+
flash. Any Python code will need to be stored on the internal flash
13
+
filesystem.
14
+
15
+
I2C pins `board.SCL1` and `board.SDA1` are not exposed and are used for onboard peripherals.
16
+
Pin `board.R_PULLUP` must be set to high to enable the `SCL1` and `SDA1` pullups for proper operation.
17
+
18
+
Pin `board.VDD_ENV` applies power to the BMI270, the BMM150, the LPS22HB and the HS3003, and must be high for them to be operational.
19
+
20
+
Pins `board.MIC_PWR`, `board.PDMDIN`, and `board.PDMCLK` are for the Nano 33 BLE Sense onboard microphone.
21
+
22
+
Pin `board.INT_APDS` is the interrupt pin from the APDS-9960.
23
+
24
+
Pins `board.INT_BMI_1` and `board.INT_BMI_2` are the two interrupt pins from the BMI270.
25
+
26
+
Pin `board.INT_LPS` is the interrupt pin from the LPS22.
27
+
28
+
Pins `board.RGB_LED_R`, `board.RGB_LED_G`, and `board.RGB_LED_B`
29
+
are the red, green and blue LEDS in the onboard RGB LED.
30
+
31
+
Pins `board.LED_G` and `board.LED_Y` are onboard green and red LEDs. `board.LED_Y` is also `board.SCK`.
