Overview

This driver module is based on the L293 dual motor driver chip which is designed to provide bidirectional drive currents of up to 1 A at voltages from 4.5 V to 36 V. This module also features an optocoupler, in order to protect the MCU from electromagnetic interference. It also features separate power rails for motor drive and logic, being able to work with 3.3 V or 5 V microcontrollers. This module is useful for driving inductive loads like DC motors, stepper motors, solenoids and other high current or high voltage loads.

Specifications

• L293 small motor driver chip
• Two integrated H bridges
• One four-phase stepper motor interface
• Terminal blocks for power supply and DC motors
• Opto-isolated interface
• 3.3V or 5V system control interface
• PCB Size: 51.8 x 39.3 mm

Note: The chip has no over-current protection so make sure that the motor current is not too large.
