Driver25PS is a new improved 2.5A Bipolar stepper motor drive board.
Specification
- Popular design using the Allegro 3977 chip
- PS (Power save input) is switchable and reduces hold current to approx 30% keeping chips, motors and power supplies cool. This function is optional and needs a compatible parallel interface to work.
- Unplugable none reversible motor connector
- Improved layout, with all connections on one side and provision for vertical mounting bracket.
- Two phase PWM operation.
- Uses Internal synchronous rectification to reduce board size and heat dissipation.
- Includes thermal shutdown, UVLO and crossover current protection.
- 1/8,1/4,1/2 or full step selectable.
- Dip switch adjustable stepper currents 1, 1.5, 2 & 2.5 amps
- Step, Direction, Enable and PS (Power save) line inputs.
- On board 5V regulator, single supply line (24V - 30V DC regulated supply recommended)
- Maximum 35V @ 2.5A per phase motor output.
- LED indicator display of step, direction, enable and power.
- Dip switch settings for step increment, enable, sleep & current.
- Board size 97 X 60 mm. FR4, immersion gold, 2oz copper, RoHS compliant.
- Loop through power connections.
Notes: Metal fixing bracket is for illustration purpose and is not included.
Controller I’C is surface mount and is supplied ready soldered to PCB in Kit.
