Dual DC Motor driver using two L293D IC. The L293D device is quadruple high-current half-H driver. The 293D is designed to provide bidirectional drive current up to 600mA a voltage from 5V to 36V. It provides 600mA +600mA on each channel suitable for mini hobby robots.  The board been designed mainly for small size robot, however this can be used for other application where two motor control required. L293D includes the output clamping diodes for protections. Each channel required two input signals PWM and DIR for full control. Separate logic supply to reduce dissipation.

Specifications

  • Motor/Logic supply 5 to 36 V
