Chapter 1. Introduction
The dsPICDEM MCSM Development Board is targeted to control both unipolar and
bipolar stepper motors with no hardware configuration changes. This flexible and
cost-effective board can be configured in different ways for use with Microchip’s
specialized dsPIC33F Motor Control Digital Signal Controllers (DSCs).
The dsPICDEM MCSM Development Board offers a mounting option to connect either
a 28-pin SOIC device or a generic 100-pin Plug-In Module (PIM). The board also has
two full-bridge inverters. The hardware is designed in such a way that no hardware
changes are necessary for 8-, 6- or 4-wire stepper motors in either bipolar or unipolar
configurations. Topics covered include:

OVERVIEW
Figure 1-1 shows a photograph of the dsPICDEM MCSM Development Board. A
dsPIC33F device uses the MOSFET driver to drive the two full-bridge inverters that
power the motor windings. The board includes various circuitries to perform the
following functions:
• Drive two motor windings with the two on-board full-bridge inverters
• Measure feedback and other analog signals (i.e., current, DC voltage,
Potentiometer and Fault signals)
• Communicate with a host computer or an external device via USB
The dsPICDEM MCSM Development Board supports terminal voltages up to 80V and
currents up to 3A. Refer to
Appendix B. “Electrical Specifications”
for more
information.
