Your motor seems to slightly exceed the current limit of the easydriver boards. You will need to adjust the max current to make sure it is below the limit of the driver board. I'm not sure if the board can easily supply its max current without additional cooling.
The Easydriver boards will be much easier to use.
Be aware, that with a coil resistance of 6.3 ohms it only takes a steady state voltage of about 5v to reach the maximum allowed current if you don't use an easydriver board.
