I have need for a stripped down AT MEGA board equivalent to  the Pro Mini board http://www.sparkfun.com/commerce/product_info.php?products_id=9218

I don't want to develop one if there is something already out there, thanks.

I haven't seen one made yet, but Seeeduino's Mega is smaller then the Arduino's mega model. It's got the same footprint as a standard Arduino board.

In that small form factor, PJRC.com has already developed the the Teensy++. The AT90USB1286 chip is compatible with the ATmega1280 chip, with built-in USB connectivity. I use the Arduino IDE to program it and run Arduino sketches on it (see http://www.pjrc.com/teensy/teensyduino.html).

Flash, SRAM and EEPROM are the same or better, but it only has 8 analog in instead of the 16 on the ATmega1280, and it has 46 digital I/O pins (9 PWM) instead of 54 digital pins (14 PWM). It supports I2C and SPI. So if you need the Mega for memory, you're fine, but if you need the maximum number of pins, you may be short.

Humm, the Teensy++ sounds tempting, and would work for now, but in the long run I would need all 16 analog inputs and the multiple uarts. So, to prevent re-development later I think I will just do the development now.

Thanks, I wasn't aware of the Teensy.

I haven't seen one available for sale, but I think this is what you are after:

Thats it!

Thanks, hopefully it will be available soon.

it's been around for a while - I was trying to get a hold of one back when it was first released but the creator decided to stop communicating with me so that never happened. If you do find where one can get one of those, please post here, I wouldn't mind having one of those myself  ;D

Jassper

I'm going to make one myself. I'll let you know how it turns out.

If all goes well, I should have baords in about 3 to 4 weeks
