Diglient Pmod DHB1 Dual H-bridge

Features and Specifications

• Dual H-Bridge capable of 1.5A RMS
• Two quadrature encoder channels for motor feedback
• Two JST 6-pin ports for connection to Digilent motor/gearbox
• Over-current protection
• Recommended 10.8 V max motor voltage
• Logic input voltage range of 2.5 V to 5 V
• 1.3 in × 1.8 in (3.3 cm × 4.6 cm) PCB size
• Follows Digilent Pmod Interface Specification Type 5

The Pmod DHB1 is a device that uses the Texas Instruments DRV8833 dual H-Bridge motor driver chip to drive two DC motors or a single stepper motor. It follows Digilent's Pmod Interface Type 5 (Dual H-Bridge) to control two independent H-Bridges by which each bridge can be driven by GPIO signals. A dual bridge motor driver solution is useful for toys, printers, and other mechatronic applications.

Pmod Series Overview

The Digilent Pmod (peripheral module) Series is a small, low-cost peripheral module that can be used with a wide range of embedded systems and development boards. It is designed to extend the capabilities of embedded systems and development boards by adding new features and functionality. The Pmod communicates with host boards using 6, 8 or 12-pin connectors that can carry multiple digital control signals, taking advantage of standard serial protocols such as SPI and I²C. This allows for more effective designs by routing analog signals and power supplies only where they are needed and away from digital controller boards.
