NEW PRODUCT – Arduino Mega 2560 R3 (Atmega2560 – assembled). This is the new Arduino Mega R3. NEW VERSION! This is the Arduino Mega R3. The Arduino Mega 2560 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.

In stock and shipping now.

  1. I wish that they would bring out the extra 14-16 processor I/O lines that are currently not connected to off board sockets to solder pads. It seems a waste to not to be able to utilize ALL of the processor pins. Also Arduino’s seem to group the processor I/O pins by function rather than by port. This means that if you want to connect a byte-wide device you probably have to perform scatter-gather I/O. The Wiring boards and IDE add a “PORT” function with I/O pins grouped by PORTS so you CAN perform byte-wide I/O. (And yes you CAN use the Wiring IDE with Arduino hardware).

  2. hey k, have you posted this in the arduino forums? the arduino team in our experience is really receptive and responsive to helpful suggestions!

  3. Yeah maybe I should. The board connections they won’t change as the shield layouts are pretty much cast in stone at this point but maybe they would add some solder pads for user added connections for the remaining pins. I may use the Wiring IDE for some applications with Arduino hardware where it would make sense as the libraries are mostly compatible between them.

Sorry, the comment form is closed at this time.
