LogicInside DC Motor / Stepper / Servo Shield for Arduino Uno Educational Electronic Hobby Kit

This Arduino compatible motor Driver shield is a full-featured products that it can be used to drive 4 DC motors or two 4-wire stepper and two 5V 'hobby' servo. It drive the DC motor and stepper with the L293D, and it drive the servo with Arduino's pin9 and pin10. Features: • 2 x L293D Motor Control Chips • Total of 4 H-Bridges for controlling 4 DC motors or 2 Stepper motors • 2 x Server ports for controlling RC Hobby Servos • The logic control voltage Vss: 4.5~5.5V • Motor Supply Voltage: 4.5 ~ 12V • Reduced control pins needed through 8-stage serial shift registers • Drive part of the operating current Io: 1.2A (0.6A per bridge) • External power connection via a screw-terminal block • Screw-Terminal blocks for connection to motors
