The Arduino board was created at the Ivrea Interaction Design Institute with beginners in electronics and programming in mind. This board began changing to meet new demands and difficulties, evolving from straightforward 8-bit boards to solutions for the Internet of Things (IoT) applications, 3D printing, wearable technology, and embedded environments. All boards are completely open-source, allowing users to construct them independently and then customize them to meet their own requirements.
What Are the Types of Arduino Boards?
There are several different types of Arduino boards, each designed for different purposes and featuring different sets of capabilities. Some of the most popular types of Arduino boards include the Arduino Uno, the Arduino Nano, the Arduino Mega, the Arduino Leonardo, and more-
Arduino Nano-
The diminutive Arduino Nano is an Arduino UNO that can fit on a breadboard. It is functionally similar to the Arduino UNO in several ways but has a smaller size factor. The absence of a DC power jack, the use of a Mini USB port rather than a USB B port, and the USB-TTL converter chip are the only significant differences from the UNO. Instead of an ATMega16U2, Nano employs an FT232, a specific USB-UART bridge chip from FTDI. Similar to UNO, it is a very popular option among developers due to its tiny size and low cost.
Arduino UNO R3-
The most well-known and often utilized development board is the Arduino Uno. An ATMega328P microcontroller powers it. It is the most often used option in the community since it is affordable, simple to learn how to use, and has a selection of prefabricated modules that make it simpler to construct new projects or prototypes. It has 14 digital I/O ports, including SPI, I2C, and UART standard communication ports, as well as 6 8-bit PWM pins, 6 10-bit analog inputs, and 6 digital I/O pins.
Arduino PRO Mini
Actually, Pro mini is a scaled-down version of Nano. It has many of the same features as an Arduino Nano, however, neither a USB port nor an internal USB-TTL bridge is included. Rather, it features a header from which the UART pins protrude. Using an external USB-UART module, we may program the Pro mini using these pins. This board is specifically designed for applications with constrained space. There are two versions of the Pro Mini: 3.3V and 5V. Due to the restrictions placed on the ATMega328 for increased stability, the CPU speed in the 3.3V version is limited to 8MHz.
Arduino Micro
The Arduino Micro is essentially a Leonardo in a small form factor breadboard-friendly sized board, similar to how Arduino Nano is a UNO in a small form factor. Its features are identical to those of the Arduino Leonardo. The absence of a DC input jack is the only difference. Arduino Micro can perform these functions similarly to HID or virtual COM port devices.
Arduino Leonardo
An ATmega32U4 chip, as opposed to the ATMega328P chip included in all of the mentioned boards, powers the Arduino Leonardo. It contains additional IO pins (20), PWM pins (7), and analog input pins (12). The ATMega32U4 has built-in USB communication, which eliminates the need for a second processor or a separate USB to UART bridge chip. This is another significant difference. This enables the board to establish a Human Interface Device (HID) or Virtual (CDC) serial / COM port connection with a computer. The bootloader and this Virtual COM port are used to program the Leonardo.
Arduino Nano Every
A next-generation board in a compact size factor is the Arduino Nano Every. The Arduino Nano is the preferred board for many projects that call for a compact and affordable solution, as we've already described. The Arduino Nano Every may be compared to an updated Arduino Nano with a lot more features. The ATMega4809, a more potent processor, powers Nano Every. We can use this board for larger programs thanks to its 200% more RAM and 50% more program capacity. We may utilize the Nano Every on a PCB without the header pins thanks to the castellated holes.
Arduino Mega2560 Rev3
Of all the boards we have discussed thus far, the Arduino Mega 2560 is the largest. It is made for applications that require a lot of peripherals or I/O. The ATMega2560, a larger and more powerful CPU, powers it. This board features 54 I/O pins (of which 15 can be used as PWM outputs), 16 analog inputs, and 4 UARTs, more than most other boards. Compared to most other basic Arduino boards, it features more flash storage and SRAM. It is most well-liked by the open-source PLC and CNC communities as well as the 3D printing communities.
What Are the Main Differences between These Boards?
The Arduino Uno is one of the most commonly used Arduino boards. It features a microcontroller, a USB port, a power jack, and digital and analog input/output (I/O) pins. The Uno is a good choice for beginners and for projects that don't require a lot of complex processing or a lot of I/O pins. The Arduino Nano is a smaller version of the Uno. It has the same microcontroller and I/O pin layout as the Uno, but it is much smaller and more compact. This makes it a good choice for projects where space is at a premium, such as when building a project into a small enclosure or when trying to minimize the size of your project.
The Arduino Mega is a larger version of the Uno. It has more I/O pins, more memory, and more processing power than the Uno or Nano. This makes it a good choice for projects that require a lot of processing power or that need to interface with a lot of external devices. The Arduino Leonardo is similar to the Uno, but it has some key differences. It has a microcontroller that is capable of emulating a keyboard or mouse, which makes it a good choice for projects that need to interact with a computer. It also has a built-in USB connection, which makes it easy to connect to a computer without the need for a separate USB-to-serial adapter.
Overall, the type of Arduino board you choose will depend on the specific needs of your project. If you're just getting started with Arduino and don't have a specific project in mind, the Arduino Uno is a good place to start. As you gain more experience and have more specific requirements for your projects, you can choose from the other available boards to find the one that best meets your needs.
