Arduino Uno

Arduino UNO is the most famous board in theArduino family after Arduino Duemilanove. Itis the latest design of the basic USB boardand one of the more stable Arduino platforms

to date. The board contains everything that amid sized 8-bit microcontroller project needsand is the standard kit for people looking tostart out in Arduino, due to its compatibilityand prevalence.

Specifications

Advantages- Improved USB interface which allows the Arduino to interface with Windows and OSX

without drivers (though Windows users still require a .inf le). - The Uno can also be recognized as an input device, such as a keyboard or mouse, which

opens up a lot of input/output possibilities for the platform. - There are a lot of shields to expend its functionality. - An open source design. The advantage of it being open source is that it has a large

community of people using and troubleshooting it. This makes it easy to nd someone tohelp you debug your projects.

- Very convenient power management and built-in voltage regulation. You can connect anexternal power source of up to 12v and it will regulate it to both 5v and 3.3v. It also can bepowered directly off of a USB port without any external power.

- A 16mhz clock. This makes it not the speediest microcontroller around, but fast enough formost applications.

Disadvantages- Limited processing power - No data storage

Arduino Mega

The Mega is the second most commonly encountered version of the Arduino family. TheArduino Mega is like the Arduino Unos big brother. Purchase the Mega when you have aclear need for the additional input-output pins and larger memory. Its ideal for those largerprojects that control lots of LEDs, have a large number of inputs and outputs. However, all ofthe added functionality comes at the cost of a slightly larger circuit board. It may make yourproject more powerful, but it will also make your project larger.

Specifications

Advantages- The Mega provides signicantly increased input-output functionality- Increased memory - 4 Serial ports - The Mega works with the majority of the shields available - Support for I2C/TWI

Disadvantages- One of the difculties of the mega board is that all the pins are different so most tutorials

who are aimed at the UNO board or the Duemilanove or Diecimila are useless becausethe Mega board pinout is different. To know which pinout is needed for the Arduino Mega2560 the arduino.cc website has a special webpage:( http://arduino.cc/en/Main/ ArduinoBoardMega2560 ) .

Arduino Nano

As its name, Arduino Nano is a compact and breadboard-friendly version board based onATmega328 processor. It is more or less same functionality as the Arduino UNO but indifferent package. Instead of using the standard USB to connect to the computer, it uses themini usb but without the power plug for external power source that built on Arduino UNO.The dimension of Arduino Nano is only 43mm x 18mm reducing the size of any robotics ormotorised project.

Specifications

Advantages- Compact and powerful

- It contains the same microcontroller (ATmega328) but in SMD form - has all the I/O pins (plus two extra analogue inputs) - Perfect for breadboarding

Disadvantages- Does not use standard Arduino shields
