SparkFun Electronics will be closed on July 3rd, 2015 in observance of Independence Day. Any orders placed after 2:00pm MT on July 2nd will be shipped out after the weekend. Thanks!
Description: Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux).
The Arduino Mega is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.
The Mega 2560 R3 also adds SDA and SCL pins next to the AREF. In addition, there are two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board. The other is a not connected and is reserved for future purposes. The Mega 2560 R3 works with all existing shields but can adapt to new shields which use these additional pins.

Although it could have been a 5 star review. I will only give the unit a 4 simply because the PCB came in a paper box with NO ESD bag around it. While this has nothing to do with sparkfun, the Arduino people should be ashamed of themselves for shipping a static sensitive piece of electronics without protection.
The Mega 2560 R3 is probably the best value for money. So many pins; I have not yet run out of inputs or outputs! Like its stable mates, the Mega 2560 is so reliable.
Started with an UNO. But my project needed just a little more sensors and programing space. The Mega worked straight out of the box as both hoped and expected.
Can’t wait to build my next project.
have used this device about a month. most of the month has been studying technical docs., learning Arduino IDE and C/C++. Anything new will be difficult at some level, however, documentation has been accurate so far. Yes, I would buy another for the next project(s).
I bought an Arduino Mega to prototype some ideas for drones (it worked great!) and was so impressed with it, and with the pyFirmata software, that I ordered four more for students to use in class.
Stuff that took me days to attempt (usually unsuccessfully) using an ordinary computer with adapters and the like, takes five minutes with Arduino. My only regret is that I didn’t try it sooner.
Sparkfun is an incredible resource for researchers, students, and hobbyists. I’ve never had a reason to complain about this or any other order I’ve made with you. Live long and prosper!
