AllMotion: Miniature Step and Direction Stepper Motor Driver EZINCH-16

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 onboard potentiometers set the MOVE and HOLD currents, and the onboard electronics automatically switch between the two current settings when pulses are detected on the STEP input.

The drive current is up to 1 Amp.

Features:

• 4 Wire input: STEP, DIRECTION, GROUND, POWER
• 1A chopper (PWM) stepper driver
• Operates from +9V to 30V
• 1" X 1" X 0.5" thick
• 1/16, 1/4, 1/2, full step; dipswitch-selectable
• Hold and move current settable with potentiometers
• Move current automatically selected when step input is active
• Hold current automatically selected upon move completion
• MilliOhm FETs allow the board to run cool at 100% current
• Accepts 24V or TTL Level Inputs
• Up to 25000 pulses per second
