Model Name/No.	Nano 33 IoT

• The Arduino Nano 33 IoT combines the Arduino Nano form factor with an easy point of entry to basic IoT and 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 Bluetooth® Low Energy device sending data to a cellphone, the Nano 33 IoT is your one-stop-solution for many of the basic IoT application scenarios.

Main features:-

• The Arduino Nano 33 IoT is Arduino's smallest board to get started with Internet of Things (IoT). Using the popular Arm® Cortex®-M0 32-bit SAMD21 processor, it also features the powerful u-blox NINA-W102 Wi-Fi module and the ECC608A crypto-chip for security.

Wi-Fi®

• The board comes with Wi-Fi® connectivity and Arduino IoT Cloud compatibility. This allows you to create IoT applications in your own projects.
• The Nano 33 IoT is Bluetooth® enabled allowing you to control peripheral devices via bluetooth and start implementing Bluetooth® Low Energy applications.
• The Nano 33 IoT comes with an IMU (LSM6DS3), combining an accelerometer and a gyroscope. Build your own motion tracking device and implement it in your projects.

operating voltage

• The microcontroller on the Arduino Nano 33 IoT runs at 3.3V, which means that you must never apply more than 3.3V to its Digital and Analog pins. Care must be taken when connecting sensors and actuators to assure that this limit of 3.3V is never exceeded. Connecting higher voltage signals, like the 5V commonly used with the other Arduino boards, will damage the Arduino Nano 33 IoT.
• To avoid such risk with existing projects, where you should be able to pull out a Nano and replace it with the new Nano 33 IoT, we have the 5V pin on the header, positioned between RST and A7 that is not connected as default factory setting. This means that if you have a design that takes 5V from that pin, it won't work immediately, as a precaution we put in place to draw your attention to the 3.3V compliance on digital and analog inputs.
• 5V on that pin is available only when two conditions are met: you make a solder bridge on the two pads marked as VUSB and you power the NANO 33 IoT through the USB port. If you power the board from the VIN pin, you won't get any regulated 5V and therefore even if you do the solder bridge, nothing will come out of that 5V pin. The 3.3V, on the other hand, is always available and supports enough current to drive your sensors. Please make your designs so that sensors and actuators are driven with 3.3V and work with 3.3V digital IO levels. 5V is now an option for many modules and 3.3V is becoming the standard voltage for electronic ICs.

Software & Cloud

• The following software tools allow you to program your board both online and offline.
• Description The Arduino Nano 33 IoT and Arduino Nano 33 IoT with headers are a miniature sized module containing a Cortex M0+ SAMD21 processor, a Wi-Fi®+Bluetooth® module based on ESP32, a crypto chip which can securely store certificates and pre-shared keys and a 6 axis IMU. The module can either be mounted as a DIP component (when mounting pin headers), or as a SMT component, directly soldering it via the castellated pads

Mega2560 Pro ATMEGA2560-16AU USB CH340G Development Board

The Mega Pro Embed CH340G / ATmega2560 board is based on the ATmega2560 microcontroller. Built on the Atmel ATmega2560 microcontroller and USB-UART interface chip CH340G. This is a great solution to get your final project on the welding prototype board.

The Mega Pro Embed functionalities are identical to the Mega 2560. Even though it is an Embed board, it is solid as stable as the Mega Board. It uses the original chip, and 16 MHz high-quality quartz resonators are present on the board. The board uses the chip CH340G as the converter UART-USB. It provides a stable data exchange result when you work at a frequency of 12Mhz (requires the driver to be installed on the computer).

You can power the board or power the pins through the MicroUSB connector. The voltage regulator (LDO) can handle input voltages from 6V to 9V (peak 18V) DC. The voltage regulator allows to use up to 18V as an input value, however, we do not recommend exceeding the recommended values aforementioned, since this can lead to excessive heat and damage the device.

While you’ll eventually need to learn to control DC motors in order to build your own robot, you’ll probably need something a little easier to get started – which is where the L298N motor driver comes in. It can control the speed and spinning direction of two DC motors.

In addition, it can control a bipolar stepper motor, such as the NEMA 17. If you want to learn more about it, check out this tutorial.

Controlling a DC Motor
We can only have full control over a DC motor if we can control its speed and spinning direction. This is possible by combining these two techniques.
PWM – to control speedH-Bridge – to control the spinning direction

PWM – to control speed

The speed of a DC motor can be controlled by changing its input voltage. A widely used technique to accomplish this is Pulse Width Modulation (PWM).

PWM is a technique in which the average value of the input voltage is adjusted by sending a series of ON-OFF pulses. This average voltage is proportional to the width of the pulses, which is referred to as the Duty Cycle.

The higher the duty cycle, the higher the average voltage applied to the DC motor, resulting in an increase in motor speed. The shorter the duty cycle, the lower the average voltage applied to the DC motor, resulting in a decrease in motor speed.

H-Bridge – to control the spinning direction

The spinning direction of a DC motor can be controlled by changing the polarity of its input voltage. A widely used technique to accomplish this is to use an H-bridge.
An H-bridge circuit is made up of four switches arranged in a H shape, with the motor in the center.

Closing two specific switches at the same time reverses the polarity of the voltage applied to the motor. This causes a change in the spinning direction of the motor.

The following animation shows the working of the H-bridge circuit.

L298N Motor Driver Chip

At the center of the module is a big, black chip with a chunky heat sink – the L298N.

The L298N chip contains two standard H-bridges capable of driving a pair of DC motors, making it ideal for building a two-wheeled robotic platform.

The L298N motor driver has a supply range of 5V to 35V and is capable of 2A continuous current per channel, so it works very well with most of our DC motors.

L298N Motor Driver Module Pinout

The L298N module has 11 pins that allow it to communicate with the outside world. The pinout is as follows:
Power Pins
The L298N motor driver module receives power from a 3-pin, 3.5mm-pitch screw terminal.

The L298N motor driver has two input power pins: VS and VSS.

VS pin powers the IC’s internal H-Bridge, which drives the motors. This pin accepts input voltages ranging from 5 to 12V.

VSS is used to power the logic circuitry within the L298N IC, and can range between 5V and 7V.

GND is the common ground pin.

Output Pins

The output channels of the L298N motor driver, OUT1 and OUT2 for motor A and OUT3 and OUT4 for motor B, are broken out to the edge of the module with two 3.5mm-pitch screw terminals. You can connect two 5-12V DC motors to these terminals.

Each channel on the module can supply up to 2A to the DC motor. The amount of current supplied to the motor, however, depends on the capacity of the motor power supply.
Direction Control Pins
The direction control pins allow you to control whether the motor rotates forward or backward. These pins actually control the switches of the H-Bridge circuit within the L298N chip.
