L293D Motor Driver Board TEC1 12706 The MQ-7 can detect CO-gasL293D Motor Driver Board The L293D Motor Driver Module is a medium power motor driver that is ideal for driving DC and stepper motors. It employs the well known L293 motor driver IC. The l293d motor driver board can turn on and off four DC motors or control two DC motors with directional and speed control. The driver greatly simplifies and improves the ease with which microcontrollers can control motors, relays, and other devices. It has a total DC
