3A Unipolar Stepper Motor Driver:
This tiny Unipolar stepper motor driver has been designed around SLA7078MPR IC from Sanken, It is unipolar stepper Motor driver can handle current up to 3 Amps, micro-stepping up to 1/16 steps. On-board Jumpers to set the Micro-stepping, Preset (Potentiometer) to set the current.
The SLA7070MPR series motor driver ICs features unipolar drivers. The clock-in type input interface allows simplified control logic, and options for built-in sense current detection and load circuit short or open protection (patent pending) provide lower loss, and lower thermal resistance.
The built-in excitation distribution circuit (sequencer) allows motor control using only the CLOCK signal for simple operations (rotate/stop), with motor speed control by frequency input into CLOCK pin. This eliminates logic signal lines required for conventional phase-input methods, and reduces demand on heavily-used CPUs.
Unipolar stepper board is high efficient stepper driver for Unipolar stepper motor been design for various application like robotics, control routers, lathes, mills, PCB drillers and engravers.
