Types Of Arduino Boards

Ivrea International Design Institute developed Arduino boards. The target market was students without a background in electronics and programming. All Arduino design specifications, schematics, and software are available to everyone. Users can make boards by following the guidelines found on Arduino’s website. ln case it is more convenient to purchase, boards ranging from simple to complex are available for purchase. Complex boards in this instance define all boards built by other people to cater for specific needs. Regardless, all boards have a micro-controller, LED, and added features.

What are Arduino Boards

Arduino board basically refers to an open-source platform that’s used for making electronics projects. The board consists of
both the microcontroller and part of the Integrated Development Environment or software that runs on the PC, used to write and upload the computer code to physical boards.

Different Types of Arduino Boards

This section discusses the different types of Arduino boards according to the level of complexity. Specific categories are entry level, enhanced features, internet of things and wearable boards.

Entry Level:

  1. Arduino Uno. Uno board is the most documented product. Ease of use makes it popular with beginners. The board uses regular USB and has CPU speed of 16MHz. The input and output voltage is 5V and 7-12V respectively.
  2. Arduino Leonard. Leonardo is a design that utilizes Atmega32u4 dataset. It has 7 PWM output pins and 12 analog inputs. The board has a built-in micro USB eliminating the need for secondary processors. Additional features include a power jack, ISCP header, and a reset button.
  3. Genuino 101. The board is classic but has latest technological features in its creation. Genuino 101 board recognizes gestures and allows control using a smartphone. It contains Intel Curie Module; high performance and low energy consumption is a guarantee. The module has two cores each with a speed of 16MHz.
  4. Arduino Esplora. The Esplora is similar to Leonardo board except it has integrated sensors and actuators. Sensors such as for light and temperature are ready-to-use. The speed of operation is 16MHz.

Enhanced Features:

1. Arduino Mega 2560

The board serves as a replacement of Arduino Mega. It has a design suitable for complex projects such as 3D designs and robotics. Mega 2560 has 54 input/output pins. 16 are analog inputs, 15 are PMW outputs, 4 are hardware series ports, a power jack, a reset button and USB connection. A regular USB cable is best for this board.

2. Genuino Zero

Genuino Zero is suitable for innovative technology such as loT devices, wearable technology or automation. The board has a 32-bit core and a full debug interface. A total of 20 pins and speed of 16MHz operates the board. The pins, however, cannot handle more than 3.3V.

3. Arduino Due

Similar to Genuino, the board is the first to be built on a 32-bit core. Arduino Due has 54 pins useful for large-scale Arduino projects. The pins do not tolerate voltage higher than 3.3V. It has a clock speed of 84MHz.

4. Arduino Mega ADK REV3

The Mega ADK REV3 is designed to work with Android. The board is an alteration of Arduino Mega. It has an operating voltage of 5V and speed of 16MHz.

5. Arduino Mo and Mo Pro

Arduino Mo is a 32-bit extension of Arduino Uno. The platform has a 32-bit core perfect for innovations. Arduino Mo is suitable for new technology and educational tools. The Mo Pro introduces a step by step debug platform.

Internet Of Things:

1. Arduino Yun

The Yun is the best for connecting network devices running Linux OS. It has 20 pins which operate at 5 volts. The board has built-in Ethernet and WiFi support. It is best to confirm WiFi functionality of the board before buying. Some countries restrict selling of WiFi-enabled devices.

2. Arduino Ethernet REV without Poe

The platform has fourteen pins; four PWM outputs and four Ethernet module pins. Only nine of the 14 pins can be used A higher voltage than 5V damages the pins. Normal speed is 16MHz.

3. Arduino Tan

The board has a 32-bit ARM Cortex Mo plus core and Qualcomm Atheros AR9342. It has internal memory of 16MB and 4GB external memory.

4. Arduino Industrial 101

The Industrial 101 is an elevation board for Arduino 101 LGA module. It supports Linux OS. The platform has five pins and an Ethernet signal on pin headers. It is suitable to use at 3.3V. Built-in DC/DC converter and WiFi are the key features.

5. Arduino Leonardo Eth

Leonardo Eth is a better version of Leonardo. It enables Ethernet Controller and has 20 pins. The unique feature about the Leonardo Eth is that designers have added pins that allow connection to shields.

6. MKR Boards

The MKR boards can be further classified into three: MKR FOX 1200, MKR WAN 1300, and MKR GSM 1400. The FOX 1200 has a two-year free subscription. It is ideal for those intending to design a loT project with minimal experience in networking and low power devices. WAN 1300 is designed to power the board using either 1.5V batteries or an external 5V power source. The GSM 1400 is similar to WAN 1300 except it cannot be powered by more than 3.3V.

Wearable Boards:

1. Arduino Gemma

The Gemma has three I/O pins two being the output and one input. An 8MHz resonator is installed within the board. Gemma uses a micro USB connection. Simply connect it to a computer using micro USB or battery power to start.

2. Lilypad Arduino

The Lilypad Arduino board is suitable for e-textiles and wearable projects. It is common to use the board to supply power, sensors, and actuators with a thread for sowing into fabric. The board has a variety of types according to the method of attaching to a computer. Examples area:

· Lilypad Arduino USB which can be attached to the computer using a micro USB cable. Unfortunately, there are no other means.

· Lilypad Arduino Main Board has 14 pins that are safe at less than 5.5V. The plug should not be fit backward as this completely
spoils the board.

· Lilypad Arduino Simple has only nine pins. It also has a JST connector and a built-in charging circuit for Lithium Polymer batteries.

· Lilypad Arduino Simple Snap is quite similar to Lilypad Arduino Simple except for conductive snaps. By using matching snaps, you can securely remove or move your projects.


If you are interested in owning an Arduino board, consider your intended purpose of use, For example, if you just want a simple board to use as a beginner then choose Arduino Uno. An advanced user might prefer Arduino Mo design to create new phone hardware. All the best!
