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
