Stepper Motor Control Board
The stepper motor control board is a sophisticated motor control for driving NEMA17,
NEMA23, and NEMA34 stepper motors rated at up to 80 V at 3 A. Key features include the
feature-rich Stellaris LM3S617 microcontroller designed for motion control applications, a
Fairchild Semiconductor power stage consisting of Fairchild's FAN73832 HVIC Driver and
FDMS3672 MOSFET, and sophisticated software to optimally control a wide range of
motors in diverse applications.
First-time users should purchase the Stepper Motor Reference Design Kit (RDK) which
includes the control board, cables, configuration software (GUI), a documentation CD, and
a sample motor. After evaluating the Stepper Motor control board, users may choose to
either customize the design or use the Stepper motor control board without modification.
Refer to the RDK-STEPPER User's Guide (available for download from
www.luminarymicro.com) for complete technical details on using and customizing the motor
control board. The Stepper board includes the Stellaris motor control and configuration
(MCC) protocol. This protocol can be replaced with any industry-standard protocol.
