This is a 9V snap that will allow you to power the Mega2560 from a battery!
So you could hook it up to a 9V or use a battery holder with AA or AAA cells
and use that instead.
The quality and construction on them is near perfect and there are no corners
cut in the design or implementation.
These MEGA2560 chips are the same devices I use
for all my development work and I stand by the quality. The Board also has
the ATMEGA16U2 usb converter. You want this on any board you use.
ATmega2560-16AU ATMEGA16U2 Board & USB Cable & 9V DC Battery snap and Plug for MEGA2560 R3
The Mega R3 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.
This is the new ATMega 2560. In addition to all the features of the previous board, the Mega 2560 now uses an ATmega16U2 instead of the FTDI chip. This allows for faster transfer rates, no drivers needed for Linux or Mac (inf file for Windows is needed), and the ability to have the board show up as a keyboard, mouse, joystick, etc. It also has twice as much flash memory.
