Measuring just 1" X 1" , the EZ Inch Stepper Driver was designed to allow users to create miniature motion control solutions.
The inputs to this drive are STEP, DIRECTION, POWER (9V-30V) and GROUND. (There is no requirement for separate 5V power). The step and direction inputs accept 5V TTL level signals, or can accept switch closures to ground. Please see the Wiring Diagram.
Two on board potentiometers set the MOVE and HOLD currents, and the on board electronics automatically switch between the two current settings when pulses are detected on the STEP input.
The drive current is up to 2 Amp.
