Whadda WPSH207 Motor Driver Shield for Arduino L293D

Whadda WPSH207 Motor Driver Shield is an add-on board for Arduino development boards, built around two L293D motor driver chips to drive DC or stepper motors.

Overview

The shield is designed to integrate with Arduino boards, providing motor control for robotics and automation projects. A 74HC595 shift register expands three control pins from the Arduino to eight output pins for managing motor direction, which conserves I/O on the main microcontroller.

Key Features

• Two L293D chips providing four independent H-bridges for flexible motor control
• Drives up to 4 bi-directional DC motors simultaneously, or up to 2 stepper motors
• Continuous current of 0.6 A per bridge, with a peak output of 1.2 A per bridge
• Motor power supply range of 4.5 V DC to 16 V DC
• Terminal block connectors for secure wiring of motor and power leads
• Two dedicated connections for 5 V hobby servos
• Separate isolated logic and motor power connections for stable operation and noise reduction

Protection Features

Pull-down resistors keep motors safely disabled during power-up sequences. Built-in thermal shutdown helps prevent overheating, and internal kickback protection diodes enhance circuit safety.

Dimensions and Weight

Dimensions are 3.3 (width), 1.5 (depth) and 4.3 (height), with a weight of 55 g.

Use this Whadda WPSH207 Motor Driver Shield when your Arduino project requires multiple DC motors, stepper motors or hobby servos, with its terminal connectors and protection features supporting a straightforward and safe build.
