0.8Amp 5V-26V DC Motor Driver Shield for Arduino (2 Channels)

This DC motor driver shield uses L298P chip which allows control of two 5 - 26V DC brush motors with 0.8Amp continuous current each channel. This shield can be directly stacked onto standard Arduino UNO, Duemilanove, Leonardo, Mega and also CIKU (PIC18F4550).We have added a few special features onto this shield. Motor power polarity protection, also fast test or manual control buttons for each channel of motor. Adding LSS05 (Auto-calibration line sensor) to Arduino will be easy as this shield comes with the socket for it.

The speed control is achieved through conventional PWM which can be obtained from Arduino's PWM output pin 5 and 6. The enable/disable of motor driver is controlled by Arduino pin 4 and 7, this is labelled as Signed magnitude control. You have option to configure it to become Locked Anti-phase which uses PWM signal to decide direction, speed and also start/stop of motor. The control modes can be configured from jumpers and also program.

The Motor shield can be powered directly from Arduino or from external power source (jumper to select). It is strongly encouraged to use external power supply to power the motor shield.
