The Melzi Ardentissimo is a full-featured Melzi board using the ATMEGA644P (ATMEGA1284P is being tested) chip used on Sanguinololu. This is a Sanguinololu firmware compatible board, though does have a couple of extra features the Sanguinololu does not - namely the extra Mosfet for the fan, and a software controllable LED. Melzi has micro SD on board as well. A full StepStick clone is on board as well negating the need for external stepper motor drivers.
