Introduction to arduino nano 33 iot, arduino nano 33 iot pinout, arduino nano 33 iot features, arduino nano 33 iot applicationsHi Guys! Hope you’re well today. Happy to see you around. In this post today, I’ll walk you through the Introduction to Arduino Nano 33 IoT.

Arduino Nano 33 IoT is mainly used in basic IoT applications. The Internet of things is one of the most exciting and robust developments in the field of information technology.

Using this technology you can interface a network of physical things with software, sensors, or other technologies to develop communication and data exchange between devices and other systems using the internet.

For example, you can control the room temperature by interfacing the sensors in your rooms with your smartphone through WiFi. Traditional systems including control systems, wireless sensor networks, embedded systems, and home automation all contribute to activating the internet of things.

Over the past two decades, networking technologies have been commonly restricted to traditional devices like desktop computers, laptops, and more recently tablets and smartphones. With the inception of innovative technologies, IoT continues to cover scores of devices into the network including medical devices, household appliances, vehicles, electric motors, traffic controls, street lights, smart TVs, and much more.

At Arduino, you can either generate your own Arduino Access Point or connect the board with any existing WiFi network.

I suggest you buckle up, as I’ll detail the Complete Introduction to Arduino Nano 33 IoT covering pinout, pin description, features, programming, and applications.

Let’s get started.

Introduction to Arduino Nano 33 IoT

  • Arduino Nano 33 IoT is a microcontroller board based on low power Arm® Cortex®-M0 32-bit SAMD21.
  • This board features a u-blox, the NINA-W10 that is a low-power chipset mainly employed to develop Bluetooth and WiFi connectivity.
  • With this device, you’ll also get a 6 axis IMU that makes this device an ideal fit for pedometers, vibration alarm systems, and the relative positioning of robots.
  • Moreover, this device contains a Microchip® ECC608 crypto chip that stores the cryptographic keys in hardware and guarantees secure and safe communication.
  • Visit WiFiNINA library reference page and get a hold of several certain examples available for Arduino Nano 33 IoT.
  • This device is completely compatible with the Arduino IoT cloud. You can use the Arduino IoT cloud for free – a simple and efficient way to guarantee safe and secure communication over all connected devices.

  • There are 14 digital I/O pins, 8 analog pins, and 11 PWM pins incorporated on board.
  • The board contains Flash memory of 256KB. This memory is used to store the Arduino Program (sketch). While the SRAM memory is 32KB that is used to produce and manipulate variables when it runs. There is no EEPROM available on this board.
  • The clock frequency of an oscillator is 48MHz which is used for the synchronization of all internal functions.

The board contains two LEDs i.e. one is a built-in LED connected to pin 13 of the board and the other is the power LED that turns on when power is supplied to the board.

Arduino Nano 33 IoT Pin Description

This is the little introduction to Nano 33. In this section, we will detail the pin description of each pin incorporated on the board.

Digital Pins

The Nano 33 board contains 14 digital pins that you can use as input or output depending on the requirement. These pins receive only two values HIGH or LOW. When pins receive 0V they are in a LOW state when they receive 5V they remain in the HIGH state.

Analog Pins

This board carries 8 analog pins. These pins can receive any value in contrast to digital pins that receive only two values i.e. HIGH or LOW.

PWM Pins

The Nano 33 board features 11 PWM pins. These pins, when activated, generate analog results with digital means.

SPI Pins

This is the serial peripheral interface that is used to develop communication between a controller and other peripheral devices like shift registers or sensors. Two pins: MISO (Master Input Slave Output) and MOSI (Master Output Slave Input) are incorporated for SPI communication between devices. These pins are used to send or receive data by the controller.

I2C Pins

The Nano 33 contains the I2C two-wire communication protocol. It carries two pins SDA and SDL. The SDA is a serial data pin used to carry the data while SCL is a serial clock line used to synchronize all data transfer over the I2C bus.

The I2C protocol is used to develop communication between two or more integrated circuits.

UART Pins

This board supports UART serial communication protocol with two pins Tx and Rx. The Tx pin is a transmission pin used to transmit serial data while Rx is a receiving pin mainly employed to receive the serial data.
