EAS Microstep is a single axis microstepping chopper driver board for stepper motors. It is based on the National Semiconductor LMD18245 3amp 55volt full bridge motor driver.
Drives 4,6 or 8 wire bipolar/unipolar stepper motors up to 3amps at 55volts per phase.
Can be flash programmed to support half/full steps plus 4, 8 or10* microstep modes.
Adjustable chopper current drive, no large external resisters required for stepper motor current limiting.
Automatic current reduction after 3 minutes of no step pulse activity.
Standard TTL step and direction inputs.
The LMD18245 driver has internal overcurrent and thermal shutdown protection.
HEATSINK is required, but is not included in the kit!
