Chapter 4. The Bipolar Stepper Add-on Board
4.1 GETTING STARTED
4.1.1 Overview
The bipolar stepper add-on (DM164130-7) allows you to drive common two-phase
bipolar stepper motors used in consumer electronics, ranging from CNCs, printers,
optical disc drives and small load positioning systems. The add-on is shipped together
with the Leadshine 39HS02 bipolar stepper motor pre-wired to plug directly into add-on
connector J3. Alternatively, any other 5-12V bipolar stepper motor can be used by
hooking it up through the J3 connector.
4.2 FEATURES
The key features of this board include the following:
Connectors:
• Male 20-pin connector (J1) to match the F1 LV Evaluation Platform
• Generic 6-pin bipolar stepper motor connector (J3)
• 5-12V power supply input connector (J2)
Typical Bipolar Stepper drive:
• Four P-type and four N-type MOSFETS comprising two full H-bridges each of
which drives one motor phase
• One sensing resistor for current measurement (R3).
Protection:
• 2x5A power fuses (F1, F2)
Power Supply:
• 3.3V voltage regulator (U1)
Parameter storage:
• 1k x 8 UNI/O

Serial EEPROM (U2)
4.2.1 What’s Included
The bipolar stepper add-on with part number DM164130-7 contains:
• Bipolar Stepper Add-on Board designed for the F1 Evaluation Platform
• Leadshine motor (P/N: 39HS02)
