Motor Driver on the chip L293D

Posted on

Driver motors on the chip L293DDesigned for small wheeled robots, the driver is ideal for robotic classes Mini-bag, following the lineand the labyrinth of disciplines. The driver is based on the chip L293D. For the driver, you can connect two motors. The driver can operate in two modes: Mode A – always served drove a high level and, therefore, engines will be spinning at maximum speed mode with a ringing in the pulse-width modulation (PWM), supplied with the controller, you can change the motor speed.

Here is the pcb layout :Motor Driver L293D PCB
