The new stepper motor control card SMC Arduino is a control board with many extras. The card raises enormously from commercially available control boards. The SMC Arduino is simply fitted onto the Arduino-base board a practical matter. You don't have numerous connections from our SMC Arduino to the green pcb wiring. By simply plugging in to the main board is the compatibility is child's play. On the basis of the integrated stepper motor power amplifiers can be connected at the same time three motors and operate. The phase currents can easily via trimming potentiometer can be adjusted. Also the appropriate micro-step mode, you can directly on the circuit board.This text is machine translated.
