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.   Logic supply - 5 VDC @ 300 mA Motor Supply - 8 to 30 VDC Connection via 10-pin Box Header for easy interface with any microcontroller development boards External or internal voltage reference option via jumper Onboard preset for current adjustment High speed switching diodes for L298 IC protection Power-On LED indicator for both the supplies Power Battery Terminal (PBT) for easy supplies and motor connection Heat sink included Four mounting holes 3.2 mm each PCB dimensions 74 mm x 71 mm
