NANO 33 IoT Development Board:

The Arduino Nano 33 IoT is the easiest and cheapest point of entry to enhance existing devices with headers and without headers to be part of the IoT and designing pico-network applications. Whether you are looking at building a sensor network connected to your office or home router, or if you want to create a BLE device sending data to a cellphone, the Nano 33 IoT is your one-stop-solution for many of the basic IoT application scenarios. The board's main processor is a low power Arm® Cortex®-M0 32-bit SAMD21. The WiFi and Bluetooth® connectivity is performed with a module from u-blox, the NINA-W10, a low power chipset operating in the 2.4GHz range. On top of those, secure communication is ensured through the Microchip® ECC608 crypto chip. Besides that, you can find a 6 axis IMU, what makes this board perfect for simple vibration alarm systems, pedometers, relative positioning of robots, etc.

Here some examples on how to get the Arduino boards to connect to: 

• Arduino's own IoT Cloud: Arduino's IoT Cloud is a simple and fast way to ensure secure communication for all of your connected Things. 
• Blynk: a simple project from our community connecting to Blynk to operate your board from a phone with little code
• IFTTT: see an in-depth case of building a smart plug connected to IFTTT
• AWS IoT Core: we made this example on how to connect to Amazon Web Services
• Azure: visit this github repository explaining how to connect a temperature sensor to Azure's Cloud
• Firebase: you want to connect to Google's Firebase, this Arduino library will show you how

Note: while most of the above-shown examples are running on the MKR WiFi 1010, both boards have the same processor and wireless chipset, which means it will be possible to replicate them with the Nano 33 IoT.

NANO Every Development Board:

This is a small, robust and powerful board with and without headers having the same classic Nano footprint loved worldwide. It can be programmed with the easy to use Arduino IDE available offline and online. Get started in minutes with thousands of sketches available in open-source or write your own: it is the perfect choice for your everyday projects.

Based on the ATMega4809 AVR processor, the Arduino Nano Every is flexible to the requirements of your design. It can be used in a breadboard when mounting pin headers, or as a SMT directly soldered on a PCB thanks to its castellated pads. An SAMD11 ARM Cortex M0+ processor acts as a high performance USB to serial converter that can be re-programmed by skilled users to expand further the applications of this board.

NANO 33 BLE Development Board:

The Nano 33 BLE ( with and without headers) is Arduino’s 3.3V compatible board in the smallest available form factor of 45x18mm. The Arduino Nano 33 BLE is a completely new board on a well-known form factor. It comes with an embedded 9 axis inertial sensor what makes this board ideal for wearable devices, but also for a large range of scientific experiments in the need of short-distance wireless communication. The Arduino Nano 33 BLE is an evolution of the traditional Arduino Nano, but featuring a lot more powerful processor, the nRF52840 from Nordic Semiconductors, a 32-bit ARM® Cortex™-M4 CPU running at 64 MHz. This will allow you to make larger programs than with the Arduino Uno (it has 1MB of program memory, 32 times bigger), and with a lot more variables (the RAM is 128 times bigger). The main processor includes other amazing features like Bluetooth® pairing via NFC and ultra low power consumption modes. The Nano 33 BLE comes with a 9 axis inertial measurement unit (IMU) which means that it includes an accelerometer, a gyroscope, and a magnetometer with 3-axis resolution each. This makes the Nano 33 BLE the perfect choice for more advanced robotics experiments, exercise trackers, digital compasses, etc.

NANO 33 BLE SENSE Development Board:

The Nano 33 BLE Sense (with and without headers) is Arduino’s 3.3V AI enabled board in the smallest available form factor of 45x18mm. The Arduino Nano 33 BLE Sense is a completely new board on a well-known form factor. It comes with a series of embedded sensors:

• 9 axis inertial sensor: what makes this board ideal for wearable devices
• humidity, and temperature sensor: to get highly accurate measurements of the environmental conditions
• barometric sensor: you could make a simple weather station
• microphone: to capture and analyse sound in real time
• gesture, proximity, light color and light intensity sensor : estimate the room’s luminosity, but also whether someone is moving close to the board

The Arduino Nano 33 BLE Sense is an evolution of the traditional Arduino Nano, but featuring a lot more powerful processor, the nRF52840 from Nordic Semiconductors, a 32-bit ARM® Cortex™-M4 CPU running at 64 MHz. This will allow you to make larger programs than with the Arduino Uno (it has 1MB of program memory, 32 times bigger), and with a lot more variables (the RAM is 128 times bigger). The main processor includes other amazing features like Bluetooth® pairing via NFC and ultra low power consumption modes.

The main feature of this board, besides the impressive selection of sensors, is the possibility of running Edge Computing applications (AI) on it using TinyML. You can create your machine learning models using TensorFlow™ Lite and upload them to your board using the Arduino IDE.
