What Arduino Board s are there? And what can you do with them?
Are you curious about which Arduino boards are available, and what you can do with them? In this article we will tell you more about a number of popular Arduino boards, starter kits and product families.
What is Arduino
Arduino is the world leader in open-source hardware & software.
The company offers a suite of software tools, hardware platforms, and documentation that enable almost anyone to be creative with technology.
Arduino is a popular tool for IoT product development and one of the most successful tools for STEM/STEAM education .
Hundreds of thousands of designers, engineers, students, developers, and makers around the world use Arduino to innovate in music, games, toys, smart homes, agriculture, autonomous vehicles, and more.
Arduino Uno
You can connect the Uno to the computer via the USB A/B port so that you can program the board.- The Uno features a 9V DC Barrel Jack connection that can be used to power the board/project.
- If you are not using an external power supply for your project you can connect your components to the 3.3V or 5V Power Pins.
- The Uno has 6 Analog Pins, each providing 10 Bits of resolution, or 1024 different values. The Pins can be used as inputs or outputs.
- The ATmega328 is the core component of the Uno. This microcontroller chip is responsible for executing code when the board is booted.
- The Digital Pins on the Uno can be set as input or output. The first 6 Pins can also be used as PWM (pulse with modulation) output.
What is it?
When people talk about Arduino they are usually actually talking about the Arduino Uno .
The Arduino Uno is the most widely used Arduino board, this is because it is suitable for both beginners and advanced users.
The Uno is based on the ATmega328 chip and has 14 digital input/output pins (6 of which can be used for PWM), 6 analog input pins, a 16 MHz resonator, a USB connection, a power jack, an ICSP header, and a reset button.
The board contains everything needed to support the ATmega328 microcontroller.
Connect the Arduino Uno to a computer with a USB cable, DC power, or use a battery to get started.
With the Arduino development software you can have your first project up and running within minutes!
If you are going to start with Arduino it is useful to start with a starter kit . A starter kit contains all the supplies and instructions to get started.
What can you do with it?
The Arduino Uno is perfect for:
- Getting Started with Programming
- Getting Started with Electronics
- Making simple projects
Arduino Mega
- You can connect the Mega to your computer via the USB A/B port so that you can program the board.
- The Mega features a 9V DC Barrel Jack connection that allows you to power the board/project.
- If you are not using an external power supply for your project you can connect your components to the 3.3V or 5V Power Pins.
- The Mega has 16 Analog Pins, each providing 10 Bits of resolution, or 1024 different values. The Pins can be used as inputs or outputs.
- The ATmega2560 is the core component of the Mega. This microcontroller chip is responsible for executing code when the board boots.
- The 54 Digital Pins on the Mega can be set as either input or output.
- The RXD and TXD Pins can be used to send and receive serial data, i.e. Rx represents data transmission while Tx was used to receive data.
- 16 Pins can be used as PWM (pulse with modulation) output.
What is it?
The Arduino Mega is the big brother of the Arduino Uno . In principle, the Mega works the same as the Uno. When you are going to make large projects and the Uno does not have enough I/O pins, you can switch to an Arduino Mega. The Mega has 54 Digital I/O pins. Up to 15 of these can be used as PWM (Pulse With Modulation) pins.
You also have 16 analog inputs available.
If you have a shield for an Arduino Uno you can also simply place it on the Arduino Mega.
What can you do with it?
The Arduino Mega is perfect for:
- 3D Printing
- CNC
- Robotics
- Extensive projects
Arduino Nano
- You can connect the Nano to the computer via the Mini USB port so that you can program the board.
- The AVR ATmega328 is the core component of the Nano. This microcontroller chip is responsible for executing code when the board is booted.
- The Nano has 8 Analog Pins. The Pins can be used as input or output.
- ICSP stands for In-Circuit Serial Programming and is a protocol used to program microcontrollers such as the PIC and the AVR chips.
- The Digital Pins on the Nano can be set as input or output. 6 of these Pins can also be used as PWM (pulse with modulation) output.
What is it?
The Arduino Nano is the smallest and breadboard-friendly version of the Uno .
The board comes with exactly the same functionalities as the Uno but in a smaller size. Thanks to the small size it is easier to work away in projects such as cosplay but also in small devices.
The Nano comes with 22 Digital I/O Pins of which 6 can be used as PWM output.
There are also 8 analog pins on it.
What can you do with it?
The Arduino Nano is perfect for:
- Beginners and Advanced
- Projects where a small form factor is required.
- Breadboard projects
The Nano family has grown!
Designed with makers in mind, the new Nano is a small, powerful and affordable solution for everyday projects.
Arduino has maintained the quality and reliability you've come to expect from them, making projects easier than ever!
The new Board s are compatible with the classic Arduino Board s . All new Nano Board s have low power consumption and are equipped with powerful processors.
Arduino MKR
What is it?
“The MKR Family boards offer different communication options to meet the needs of the most demanding use cases, giving users, especially professionals, one of the widest options on the market of certified products.”
– Massimo Banzi
What can you do with it?
The Arduino MKR Board s are perfect for:
- Advanced & Professional
- Projects where a small form factor is required.
- Projects that require wireless connectivity
Grab an MKR board and mix and match with your choice of shields and carrier boards to quickly and easily create custom hardware configurations for IoT solutions. It’s as easy as making a sandwich!
These are the most popular Arduino Board s . Arduino has many other boards.
You can find more information about this on the Arduino product pages .
