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
