Measuring just 1" X 1" , the Intelli-INCH Stepper Driver + Controller was designed to allow users to create miniature motion control solutions with no programming.
The inputs to this drive are GO LEFT, GO RIGHT, LEFT LIMIT, RIGHT LIMIT AND POWER (9V-30V) and GROUND. (There is no requirement for separate 5V power.) The 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 current and the SPEED. Current is automatically reduced to one third of the move current when not moving. A SLEEP_BAR Input when grounded reduces the current draw to less than 2mA, allowing the drive to be used in battery powered applications.
