The Mega 2560 R3 works with all existing shields but can adapt to new shields which use these additional pins.

Honestly, I found this more convenient that the other.

Please note that I2C is not located on the same pins on the Mega 2560 board (20 and 21) as the Duemilanove / Diecimila boards (analog inputs 4 and 5).Rather then requiring a physical press of the reset button before an upload, the Mega 2560 is designed in a way that allows it to be reset by software running on a connected computer.

Three screw holes allow the board to be attached to a surface or case.

Additionally, there are two latest pins located near the RST pin. The built-in USB port is very convenient for development work and also powers the Arduino board. It came nicely packaged in a box, was very easy to assemble and it even looks much more stylish than I expected. *The Arduino Mega 2560 has 70 total available I/O lines; all of them can function as digital I/O lines, and sixteen of them can be used as analog inputs. The product is very good though there are a couple of points I would like to make. I bought this for an Elegoo MEGA2560 R3 and it fits perfectly, while leaving all the pins easily accessible and it even has a reset button. SunFounder Mega 2560 R3 is an ATmega2560 micro-controller board. The RX and TX LEDs on the board will flash when data is being transmitted via the ATmega8U2/ATmega16U2 chip and USB connection to the computer (but not for serial communication on pins 0 and 1).The Mega 2560 also supports TWI and SPI communication.

It is based on the AT Megas that I am already so familiar with and the programming is based on Java rather than C because of the bootloader, and since Java is my preferred and most professed language I am quite pleased with that! Customer Reviews If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may become unstable.

The two tiny pieces are a little trickier. Arrived quickly, and does exactly what it says on the tin. I would suggest to anyone to buy the MEGA 2560 version of ARDUINO when learning to use/code Arduino projects ... any prototyping test items that you can do on an UNO you can do on a MEGA; however, with a Arduino MEGA 2560 you can do so much more with the extras it provides.

of them seem to work fine. This is a great solution to keep the board clean and prevent accidental shorting.

The compiler's use of the heap is the major issue as I have had it grow into the stack, with resultant disaster to the program. While it is programmed to ignore malformed data (i.e. their stuff is 100% compatible with genuine Arduino hardware.

Overall though, I still give it a five-star rating as a GREAT little mC. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The Arduino Software (IDE) includes a serial monitor which allows simple textual data to be sent to and from the board.
