The Board

Like all Nano form factor boards, Nano 33 BLE Sense does not have a battery charger but can be powered through USB or headers.
NOTE: Arduino Nano 33 BLE Sense only supports 3.3V I/Os and is NOT 5V tolerant so please make sure you are not directly connecting 5V signals to this board or it will be damaged. Also, as opposed to Arduino Nano boards that support 5V operation, the 5V pin does NOT supply voltage but is rather connected, through a jumper, to the USB power input.

Power Consumption

Functional Overview

Board Topology

Processor
The Main Processor is a Cortex M4F running at up to 64MHz. Most of its pins are connected to the external headers, however, some are reserved for internal communication with the wireless module and the on-board internal I2C peripherals (IMU and Crypto).
NOTE: As opposed to other Arduino Nano boards, pins A4 and A5 have an internal pull-up and default to be used as an I2C Bus so usage as analog inputs is not recommended.

Crypto
The crypto chip in Arduino IoT boards is what makes the difference with other less secure boards as it provides a secure way to store secrets (such as certificates) and accelerates secure protocols while never exposing secrets in plain text. Source code for the Arduino Library that supports the Crypto is available [8]

IMU
Arduino Nano 33 BLE has an embedded 9 axis IMU which can be used to measure board orientation (by checking the gravity acceleration vector orientation or by using the 3D compass) or to measure shocks, vibration, acceleration and rotation speed. Source code for the Arduino Library that supports the IMU is available [9]

Barometer and Temperature Sensor
The embedded Barometer and temperature sensor allow for measuring ambient pressure. The temperature sensor integrated with the barometer can be used to compensate the pressure measurement. Source code for the Arduino Library that supports the Barometer is available [10]

Relative Humidity and Temperature Sensor
Relative humidity sensor measures ambient relative humidity. As the Barometer, this sensor has an integrated temperature sensor that can be used to compensate for the measurement. Source code for the Arduino Library that supports the Humidity sensor is available [11]

Digital Proximity, Ambient Light, RGB and Gesture Sensor
Source code for the Arduino Library that supports the Proximity/gesture/ALS sensor is available [12]

Gesture Detection
Gesture detection utilizes four directional photodiodes to sense reflected IR energy (sourced by the integrated LED) to convert physic

Proximity Detection
The Proximity detection feature provides distance measurement (E.g. mobile device screen to user’s ear) by photodiode detection of ref

Color and ALS Detection
The Color and ALS detection feature provides red, green, blue and clear light intensity data. Each of the R, G, B, C channels have a U

Digital Microphone
The MP34DT05 is an ultra-compact, low-power, omnidirectional, digital MEMS microphone built with a capacitive sensing element and an IC interface. The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process dedicated to produce audio sensors

Power Tree
The board can be powered via USB connector, VIN or VUSB pins on headers.
NOTE: Since VUSB feeds VIN via a Schottky diode and a DC-DC regulator specified minimum input voltage is 4.5V the minimum supply voltage from USB has to be increased to a voltage in the range between 4.8V to 4.96V depending on the current being drawn.

Board Operation

Getting Started – IDE
If you want to program your Arduino Nano 33 BLE while offline you need to install the Arduino Desktop IDE [1] To connect the Arduino Nano 33 BLE to your computer, you’ll need a Micro-B USB cable. This also provides power to the board, as indicated by the LED.

Getting Started – Arduino Web Editor
All Arduino boards, including this one, work out-of-the-box on the Arduino Web Editor [2], by just installing a simple plugin. The Arduino Web Editor is hosted online, therefore it will always be up-to-date with the latest features and support for all boards. Follow [3] to start coding on the browser and upload your sketches onto your board.

Getting Started – Arduino IoT Cloud
All Arduino IoT enabled products are supported on Arduino IoT Cloud which allows you to Log, graph and analyze sensor data, trigger events, and automate your home or business.

Sample Sketches
Sample sketches for the Arduino Nano 33 BLE can be found either in the “Examples” menu in the Arduino IDE or in the “Documentation” section of the Arduino Pro website [4]

Online Resources
Now that you have gone through the basics of what you can do with the board you can explore the endless possibilities it provides by checking exciting projects on ProjectHub [13], the Arduino Library Reference [14] and the on line store [15] where you will be able to complement your board with sensors, actuators and more.

Board Recovery
All Arduino boards have a built-in bootloader which allows flashing the board via USB. In case a sketch locks up the processor and the board is not reachable anymore via USB it is possible to enter bootloader mode by double- tapping the reset button right after power-up.
