A 6-branch stepper motor can be operated at this kit. The kit works without computer. For motors 6 - 12 V/DC, max. branch current 1,5 A. Adjustable impulse sequence approx. 15 - 240 per second. In order to switch over the sense of rotation of the motor, a switch 2 x change over is required (not included in the kit). The operating voltage depends on the motor which is used respectively (6 - 12 V/DC Operating voltage 6 - 12 V/DCMax. phase current 1,5 AFor stepper motors 6-phases Impulse sequence adjustable from approx. 15 - 240 HzBoard dimensions approx. 55 x 55 mm
