ARDUINO NANO 33 BLE SENSE is the 3.3V enabled Arduino board in the smallest available size: 45x18mm! ARDUINO NANO 33 BLE SENSE is a completely new board.
It comes with a set of built-in sensors:
9-axis inertial sensor: what makes this board ideal for wearable devices
Humidity and temperature sensor: to get extremely accurate measurements of environmental conditions
Barometric sensor: you could make a simple weather station
Microphone: to capture and analyze sound in real time
Light intensity sensor: estimates the brightness of the room, but also whether someone is moving near the board
ARDUINO NANO 33 BLE SENSE is an evolution of the traditional Arduino Nano, but features a much more powerful processor, Nordic Semiconductors' nRF52840, an ARM® Cortex ? -M4 32-bit CPU running at 64 MHz. This will allow you to create larger programs than the Arduino Uno (it has 1 MB of program memory, 32 times larger) and with many more variables (RAM is 128 times larger). The main processor includes other amazing features such as Bluetooth® pairing via NFC and extremely low power consumption modes. Embedded Artificial Intelligence The main feature of this board, besides the impressive selection of sensors, is the ability to run Edge Computing (AI) applications on it using TinyML. You can create your own machine learning models using TensorFlow ? Lite and upload them to your board using the Arduino IDE.
If you have used Arduino Nano in your projects in the past, the Nano 33 BLE Sense is a pin equivalent replacement. The code will still work, but remember, it runs at 3.3 V. This means that you need to revise the original design in case it is not 3.3V compatible. Other than that, the main differences from the classic Nano are: a better processor, a micro-USB connector, and all the sensors mentioned above. You can get the board with or without headers, what will allow you to incorporate the Nano inside all kinds of inventions, including wearable devices. The board comes with doweled connectors and no components on the B-side. These features allow you to solder the board directly onto your design, minimizing the height of the entire prototype. Oh, and did we mention the improved pricing? Thanks to a revised manufacturing process, the Arduino Nano 33 BLE Sense is truly cost-effective ... what are you waiting for? Upgrade now!
