The Arduino Mega 2560 is a direct upgrade on the original, powerful Arduino Mega, and is often affectionately nicknamed “The Big Boy” of the Arduino Range. This is because it is one of the largest boards belonging to the Arduino family, and has the power to match its size. While most other boards offer pin counts of between 10 and 24, the Mega has a whopping 54 digital I/O pins. Additionally, whilst other boards range between 8KB and 128KB flash memory, the Mega 2560 outshines them with 256KB – demonstrating that it’s the ideal board for large projects.

When Arduino designed the Mega 2560, they intelligently kept the consistent width, in relation to other boards like the Arduino Leonardo and Duemilanove, so that it would be compatible with almost all previous and future Arduino Shields. Additionally, all of the core components are in similar positions to similar types of Arduino boards, ensuring that makers who are upgrading their Arduino platforms can still utilize a majority of the Arduino Uno, Duemilanove and Diecimila shields they have.

The Arduino Mega 2560 is based on the ATmega2560 chip and, in addition to the 54 digital I/O pins and 256 KB flash memory, also has 16 analog inputs, a USB connector, power jack, ICSP header and 4 UARTs – all running through a 16MHz Crystal Oscillator. 15 of the I/O pins can be utilized as PWM outputs and a reset button is conveniently installed for users who need both the manual version as well as the auto-reset functionality. This feature set makes the Mega 2560 a tough competitor to beat, and is why it’s commonly considered to be the best board available for large projects that require the power.

Typical Applications for the Arduino Mega 2560:

The sheer power of the Arduino Mega 2560 allows makers to truly step up their game in terms of the size and scope of projects, as having one of these boards can be likened to having two to four other boards working together. This makes it ideal for larger projects where numerous input and output pins, large memory reserves and an efficient cache of RAM is required. And rather than complicating your circuits with multiple boards working together, you can efficiently achieve the same results with a single Arduino Mega 2560.

Because of the power and versatility of this board, the simpler projects are typically larger and more complex than basic projects involving other boards, and include:

  • An SMS-based home automation systems with five or more channels
  • A “Track ME” box that supplies a current GPS location to whoever calls it
  • Light controller platforms for fixed or temporary installations of lighting and sound
  • A Star Trek “Tricorder”, which monitors and displays the temperature and other environmental values – as well as a few fictional ones as well

As you can imagine, if these are the more basic projects, then the advanced projects are on a whole new scale. For those looking to truly step up their game, however, more complex projects include:

  • A self-replicating open-source 3D printer – controllable of course via an online platform
  • Augmented Reality integration on a drone to fly first person and react to birds or other dangers with physical movement
  • An automated controller for fans, indoor heating or air-conditioning systems to monitor the temperature and react accordingly – keeping you comfortable year-round
  • A personally-designed and customized pinball machine, complete with bumpers, spinners and an LCD score screen

It should be obvious by now how powerful the Arduino Mega 2560 can be, and why it’s being utilized for so many different complicated projects. Not only does it offer more processing power, RAM and other power-based benefits, it also offers a whole new level of functionality with 54 I/O pins and 15 PWM channels. So find a project that you would be excited to take on and discover for yourself precisely what makes these boards the first choice for large, complex and exciting Arduino projects.

Arduino Mega 2560

When it comes to building unique electronics projects, there are few better ways to do it than with Arduino. Founded with the intent to make electronics prototyping accessible to all, regardless of age, culture, sex or any other factors, Arduino is one of the world’s leading designers and manufacturers of open-source hardware and software.

Some of the leading microcontroller boards that Arduino has produced include the classic Arduino UNO, as well as many variations with different specialisations and specifications. Some of the most popular Arduino boards – which we stock of course – are the Arduino Mega, Leonardo, Due, Micro, Nano, Mini, as well as the unique Arduino LilyPad. And with these boards at hand, as well as a Shield or two, you can craft thousands of different projects, with each one being tailored to your specific needs, wants and personal tastes.
