Description
The VNH5019 Dual Motor Driver Shield is a robust, industrial-grade power management solution for Arduino and compatible platforms. Equipped with two ST VNH5019 motor drivers, this shield is capable of driving two high-current, bidirectional brushed DC motors with ease. It features an impressive operating voltage range of 5.5V to 24V, delivering a continuous 12A (30A peak) per channel. For applications requiring extreme torque, the outputs can be combined to drive a single motor at up to 24A continuous (60A peak).
Engineered for professional robotics, this shield integrates essential protection circuitry, including reverse-battery FETs and diagnostic current-sense feedback. The flexible design allows users to customize pin mappings, making it adaptable to complex system architectures. Whether you are building heavy-duty rovers, automated machinery, or high-performance robotic arms, the VNH5019 provides the power and control reliability necessary for professional development.
Key Features
- Extreme Current Handling: Provides 12A continuous current (30A peak) per channel; can be bridged for 24A continuous (60A peak) single-motor operation.
- Advanced Driver ICs: Utilizes dual ST VNH5019 drivers with built-in current sensing (140 mV/A).
- Wide Voltage Range: Operates efficiently between 5.5V and 24V DC.
- High-Frequency PWM: Supports ultrasonic PWM frequencies (up to 20 kHz) for silent operation and smooth torque control.
- Logic Level Flexibility: Fully compatible with both 3.3V and 5V logic systems (logic high threshold at 2.1V).
- Comprehensive Diagnostics: Integrated status LEDs for output monitoring and dedicated current-sense pins for real-time load analytics.
- Customizable Configuration: Shield headers are adjustable, allowing users to remap pins to avoid conflicts in complex Arduino stacks.
Industrial Utility
- Flexible Power Delivery: Shield can optionally power the base Arduino board, simplifying system wiring in robotic chassis.
- Modular Connectivity: Includes high-quality terminal blocks for secure, high-current power and motor connections.
- Software Ease-of-Use: Supported by dedicated Arduino libraries, significantly reducing development time for motion control logic.
