This L293D motor driver shield is described as probably one of the most versatile shields on the market, since it combines 4 DC motor or 2 stepper motor connections with 2 dedicated servo connectors on a single Arduino-compatible board. Using the L293D chip's 4 H-bridges, each rated at 0.6A continuous (1.2A peak) with thermal shutdown protection, it can drive up to 4 bidirectional DC motors, each with its own 8-bit speed setting, or up to 2 stepper motors, whether unipolar or bipolar.
The 2 servo connections are wired to the Arduino's own high-resolution dedicated timer, which gives smoother and more precise servo positioning than a software-timed approach, and works with standard 5V hobby servos.
Motors connected to the shield can run anywhere from 4.5VDC to 25VDC, a wide enough range to cover most small hobby DC motors, gear motors and steppers used in robotics projects. It is compatible with Arduino Mega, Diecimila, Duemilanove and UNO boards, using the standard Arduino pin layout, and uses pins 9 and 10 for its own control logic alongside the L293D chip.
Because it handles both DC motors, steppers and servos from one shield, it suits projects that would otherwise need two or three separate driver boards stacked together, simplifying the wiring in a robot with mixed actuator types.
Builders combining wheels, a pan-tilt camera mount or gripper servos, and possibly a stepper-driven mechanism on the same robot will find this shield's mix of motor and servo outputs convenient, avoiding the need for several separate driver modules.
