This product is able to drive a wide range of stepper motor, from NEMA 17 to NEMA 42 with a maximum output current of 6[A]/phase and 48[VDC]. The board is developed in Switzerland. We want offer a open source stepper motor driver board with high current capabilities and a very smooth controller provided by the Texas Instruments®‘s motor driver IC. By simply change the MOSFET transistor, or by add a cooler, the board can easily handle more current. This board is designed to be easily and fast installed without difficult parameters.
