L293D 4-channel Stepper Motor Driver Shield for Arduino Mega 2560 and UNO R3 / Diecimila/Duemilanove



This shield is simply plugged onto an Arduino board and allows to control up to 4 DC motors, 2 stepper motors or 2 servo motors. The powerful and reliable L293D chip that distributes the load serves as an H-bridge. This allows you to easily use DC motors and power supplies up to 36V.

The proven design allows motors to be easily connected and controlled by an Arduino and is particularly suitable for fast prototyping. This shield is also suitable for beginners, so there are numerous libraries, instructions and example sketches that make controlling the direction or speed of motors child's play. We especially recommend the Adafruit Motor Shield Library (AFM), which you can download from the Arduino IDE.
