High Current Bipolar Stepper Motor Controller electronic circuit diagram

Specifications

High Current Bipolar Stepper Motor Controller kit is based on chopper drive. Chopper drive is a method of providing a constant current source to a device. Chopper drive allows for use of higher voltage power supply for better performance and higher speed. It is uses SGS Thomson's L297 and L298 controller IC's.
