It is a unipolar stepper Motor driver that can handle current up to 3 Amps and has micro-stepping up to 1\/16 steps. On-board Jumpers are available to set the Micro-stepping and Preset (Potentiometer) to set the current.\u003c\/p\u003e\n\u003cp\u003eThe\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eSLA7078MPR\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eseries 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eUnipolar stepper board is a high efficient stepper driver for Unipolar stepper motor and it has been designed for various application like robotics, control routers, lathes, mills, PCB drillers and engravers.\u003c\/p\u003e\n\u003cp\u003eThis board has been designed to be used in two ways, Stand Alone and Microcontroller Interface or Auto Half Current.\u003c\/p\u003e\n\u003ch3\u003eStand Alone\u003c\/h3\u003e\n\u003cp\u003eJust to Rotate Motor normally bellow inputs required:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePulse (Step Pulse In) Frequency\u003c\/li\u003e\n\u003cli\u003eDirection\u003c\/li\u003e\n\u003cli\u003e5V DC\u003c\/li\u003e\n\u003cli\u003eGND\u003c\/li\u003e\n\u003cli\u003eSYNC and REF doesn’t Required for this operation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMicrocontroller Interface or Auto Half Current\u003c\/h3\u003e\n\u003cp\u003eFor Micro-Controller Interface or Auto Half Current (while Motor is in Hold-State):\u003c\/p\u003e\n\u003cp\u003eUsually In Motion control and CNC application stepper motor driver required auto Half Current function specially while motor is not moving and it’s in hold-state.
