Is there ATMega1280/2560 based Arduino Nano?

Hi,

I'm looking for a bigger Arduino (bigger in term of more Flash memory), but it should be small in size (like the Nano, and yes, even the 2560 physical size is almost bigger than the whole nano... ;) ). I know the ATMega 1280 / 2560 have more pins but this isn't really necessary for my plannings.

Has someone build this yet?

Regards, Nils.

The atmega2561 has 64 pins rather than 100; so should be more inline with a small board...

The biggest small board that I know of is the sanquino, it uses a 644P and has the following and 2 serial ports

RAM size =4 K FLASH size =63 K EEPROM size =7FF bytes

Maybe not exactly what you’re looking for since it’s not an Arduino, but it’s cheap and might match your size requirements:

You’ll need an avr-isp to flash the arduino bootloader into it (you can use another Arduino for that if you like). I can also recommend buying a usb<->serial cable from dx (maybe something like http://www.dealextreme.com/details.dx/sku.24512, but they have others too).

There was a post on hackaday (http://hackaday.com/2008/11/27/atmega-controller-wiring-upgrade/) a while back about a guy who converted a similar board.

I made a board based on the 2560. It is organized differently than the Arduino boards, in that all of the data ports are broken out individually rather than by pin function. I call my board the InterfaceGenie. I do not have a working bootloader, that will be a project for when I have some development time. I can post the eagle files if you are interested.

Can you put a link to a web-site in order to have a look at it, please? ;)

You can check out the MegaMini I created. A small version of the regular Mega. It is available with either the Atmega1280 or Atmega2560. It is approximately 1 x 3 inches and includes an onboard regulator and USB interface.

consider the teensy++ at prjc.com as well. It looks like he will be able to ship again them in a couple of wks. I haven't tried loading over 64K on them and I'm not entirely sure that his custom loader handles over 64K.
