Arduino Mega: bigger, more powerful, still blue.

We’re happy to announce the release of the Arduino Mega, a larger, more powerful Arduino board. It’s based on the on the ATmega1280 (datasheet), which has 128 KB of Flash (program) memory, 8 KB of RAM, and 4 KB of EEPROM. The board has 54 digital pins (of which 14 provide PWM output), 16 analog inputs, 4 hardware serial ports, I2C, and all other goodness you expect from an Arduino board. The Mega is compatible with most shields designed for the Duemilanove, and includes the same automatic power selection, auto-reset on upload, and pre-burned bootloader.

To use the board, you’ll need to download Arduino 0015, now available from the download page (Linux version coming soon). Just select Arduino Mega from the Tools > Board menu and you’re good to go. The reference pages for individual functions will be updated over the next few days to reflect the capabilities of the Mega.

The Mega will be appearing soon at distributors throughout the world. Check the buy page for the one closest to you.

    Very nice!

    I can’t wait to see what types of robotics will be enabled by virtue of making this board official and supported. Thanks for continuing to provide the community with the resources that it needs and wants!

    I think, here’s a forgotten closing of an -Tag, because after this article everything’s written italic (I use Firefox 3). Maybe you could solve that?

    Thanks for catching that, Jan, should be fixed now.

  12. Roland Says:

    The Mega is excellent. But next time, how about increasing the clock rate? Surely you can do better than 16MHz? Other microprocessors have long since left that behind. Thanks.

    is it possible to make a 256 monome clone with one Arduino Mega

  14. dcuartielles Says:

    The chip on mega, as well as the 328 and 168, can make it up to 20MHz. We kept it this way (16MHz) to reduce the possible problems with upgrading all the existing software both for us and for all the existing Arduino compatible boards and shields.
