The Big Easy Driver, designed by Brian Schmalz, is a stepper motor driver board for bi-polar stepper motors up to a max 2A/phase. It is based on the Allegro A4988 stepper driver chip. It’s the next version of the popular Easy Driver board.
Each Big Easy Driver can drive up to a max of 2A per phase of a bi-polar stepper motor. It is a chopper microstepping driver which defaults to 16 step microstepping mode. It can take a maximum motor drive voltage of around 30V, and includes on-board 5V/3.3V regulation, so only one supply is necessary. Although this board should be able to run most systems without active cooling while operating at 1.4-1.7A/phase, a heatsink is required for loads approaching 2A/phase. You can find the recommended heatsink in the related items below.
Note: This product is a collaboration with Brian Schmalz. A portion of each sales goes back to him for product support and continued development.

Questions on Big Easy Driver
20/11/15 00.26 riesco a controllare due motori: 341207 1207 - Motore Stepper bipolare NEMA-14 35x26mm
in maniera indipendente? dovrei farli girare anche in direzione diversa uno dall'altro con una scheda arduino UNO.
questa scheda controlla un solo motore, per due motori occorrono due schede, informazioni per il collegamento https://learn.sparkfun.com/tutorials/big-easy-driver-hookup-guide
