Arduino boards are one of the widely used boards in education to scientific research programs. These boards were designed in the IIDI or Ivrea Interaction Design Institute so non-technical students can also understand the field. From that time, these boards started meeting the requirements of various users. They set up several opportunities, challenges, and other requirements.Nowadays, these boards are used in IoT applications, 3D printing, and many other applications. These boards are completely open-source, and they also have various types. Thus, in this article, we will try to understand various types of Arduino boards.What Are Arduino Boards?The boards are not any microcontrollers and are also an open-source platform for electronic needs. Arduino boards are the PCB that has inbuilt LEDs, microcontrollers, and tons of other connections. The profession can use these boards in input and output operations such as controlling the motor device, sensors, and other devices.Types of Arduino Boards1. Arduino UNO (R3)This is one of the commonly used types of Arduino board that uses the ATmega328P based microcontroller. This is the simple-to-use Arduino board, and these boards are straightforward to use. Here you can find the 14 I/O pins, and out of 14 pins, six are used in PWM or pulse width modulation output. And from the remaining, the six are used for analog units, one used in the reset button, USB connection, and power jack. In this board, the user can find all the necessary things that need to hold the microcontroller. It can also be simple to attach.2. LilyPad ArduinoThis Arduino board is used in wearable clothing because it is designed as wearable textile technology. It was developed by SparkFun and Leah that has a smooth back with a lot of connection pads. And the outstanding feature of this board is that it can sew easily without any damage to the board. In this board, the user can also find the I/O, sensor, and power boards. As these boards are primarily used in wearable textile products, hence it also is washable.3. Arduino RobotArduino Robot is also a type of Arduino board that is also known as a tiny computer. The primary use of these boards is in the robotics that contains the speakers, two motors, SD card reader, encompass, and five-floor sensor. This board also has some other features and devices that make it compatible to use in robotics.4. Arduino DueThe Due Arduino board is based on the ARM Cortex-M3, and it is one of the first microcontroller boards from the side of Arduino. This board comes with 54 I/O pins and many other pins to connect with the various devices. It can be damaged if more than a 3.3V power supply; hence, this board needs to keep the power at 3.3V. Generally, the USB cable is sufficient to connect this board with the computer. And when it comes to power, then an AC to DC adapter is used. Moreover, it has two major ports, such as USB and programming.5. Arduino Red BoardThis board is programmed with the help of a USB cable and mini-B board used in the IDE software of Arduino. This type of Arduino board works perfectly with the windows eight operating system and does not require any modification. So, to make this board, the FTDI chips with USB are used, and from the backside, it is flat. Designing the red board is quite simple for the project. For uploading the program, the user can just plugin and select the options from the menu setting.6. Arduino EthernetThis board is based on the microcontrollers like ATmega328, and it has five pins for analog connection. On this Arduino, board users get 14 I/O pins, oscillator, Rj45 connection, ICSP header, and many other options for connection. Here the connection with the network can be executed using the ethernet network technology.7. Arduino Mega (R3)You can consider the Arduino Mega (R3) as the big version of Arduino’s UNO board. It has many I/O pins and is suitable to use as PWM. Moreover, there is a USB, reset button, a power jack, and another essential connection option. It also has a feature to connect with a computer using the USB device and can be controlled with an AC to DC adapter. This board becomes very useful if the programmer needs many pins for the connections.8. Arduino NanoIn this type of Arduino board, the ATmega628 or ATmega328P can be used. And it can be connected with the network same as the UNO board from the side of Arduino. These Arduino boards are compact in size, reliable, and offer maximum flexibility for the user. In many IDE projects, it can be the perfect choice to work with because the size of this board is smaller than the UNO board.9. Fastest Arduino BoardIf you were looking for the Fastest Arduino Board, then your wait is over. Because this board is similar to Arduino Mega and UNO. It includes a 320 Mhz microcontroller unit. It also has the cortex M-7 that provides the fastest experience among the other Arduino boards. Many users use this ideal board for projects that need a robust microcontroller unit with 400Mhz support.10. Arduino LeonardoIt is one of the first development boards that have one microcontroller along with a USB. These boards are very cheap and also simple to complete the project using these boards. It can follow the direction provided by the keyboards and the mouse of the keyboards and can also be directly connected using the USB cable.11. Arduino Pro MicThis board is another type of Arduino board, and it is similar to the mini-board from the side of Arduino. The ATmega32U4 can be used in this board, and it consists of 12 pins for the I/O unit. This board is comparatively smaller and can be an ideal board for projects that need mini boards.ConclusionSo, in this article, we understood Arduino boards and some significant types of Arduino boards. We cover some major types like Arduino Due, Arduino Red board, Arduino Mega (R3), and Arduino Nano. Thus, if you like this exciting information about the types of Arduino boards, then do comment and share it with your friends.
