Stepper Motors Stepper Motor Control Do you need exact position control with great holding torque? If so, then a stepper motor is the best solution. While nearly every MCU or DSC from Microchip can drive a stepper motor, some are better suited for this than others.

Key features include four MOSFET drivers motor current limit, debug header, and pin header connector for the motor and power supply. F1 Bipolar Motor Add-On for the F1LV Evaluation Platform (DM164130-7) The Bipolar Stepper Motor Add- On is a simple development accessory that plugs directly into the F1 LV Evaluation Platform and incorporates all the components necessary to implement Bipolar Stepper Motor control. Key features include four MOSFET half bridge circuits, motor current limit sense, debug header, and pin header connector for the motor and power supply. dsPICDEM™ MCSM Development Board (DM330022) dsPICDEM MCSM Stepper Motor Development Board Kit (DV330021) This development board is intended for low-voltage (up to 80 volts at 3 amps) 2-phase uni-polar or bi-polar stepper motor (4, 6 or 8 wire) applications. It provides a low-cost system for users to evaluate and develop applications using dsPIC33F motor control DSCs via a Plug-In Module (PIM) or 28-pin SOIC socket. A USB serial interface for RTDM is provided. Feedback support includes current and voltage. Demo software to run motors in open-loop or closed-loop with full or variable micro-stepping is provided. A DMCI/RTDM GUI for controlling step commands, motor parameter input and operation modes is included. The kit includes a stepper motor and a 24-volt power supply. PICkit™ 3 Debug Express, MPLAB® ICD 3 In-Circuit Debugger or REAL ICE™ In-Circuit Emulator is required for programming or debugging operations. MTS2916A Stepper Driver Evaluation Board (ADM00308) This evaluation board incorporates features through the implementation of push button switches and a variable speed input potentiometer to exercise a stepper motor in Full-Step, Half-Step, Modified Half-Step and Micro-stepping modes.
