DTMF module

This motor driver board is designed to work with l293d ic. The l293d is a popular motor driver ic designed to provide bidirectional drive currents of up to 600-ma at voltages from 4.5 V to 36 v. Compact l293d motor driver board makes it much more convenient to use. With terminal blocks for connecting motors andamp. power supply and berg sticks for control signals from microcontroller this is most commonly used driver circuit in robots. This can control 2 dc motors, their direction using control lines and their speed using pwm.
