Step Motor Controller and Driver for OEM applications with 1.5A driving capability. Product Description The BSD-01P module is a controller and a step motor driver on one small board. This unique approach is specifically useful in variety of OEM applications. In many cases, this is the only electronic device needed to build a complete system. The BSD-01P is suitable for driving bipolar and unipolar step motors from 25mA to 1.5A and up to 24V. Driver can operate in one of 5 stepping modes: Full-, Half-, Quarter-, Eighth or Sixteenth-step without requiring any phase-sequence tables, high frequency control lines or complex interfaces to program.
