L293D 4 channel MOTOR DRIVER for 4WD robot car driver

This drive module can directly drive four DC motors, which is the best choice for 4WD 4 drive car chassis. 

The driving battery is large, up to 1A. The motor current of a general smart car is only 100-300MA,

which is enough to meet the control needs. At the same time, there is a two-way stepper motor interface,

which can drive a two-way five-wire four-phase stepper motor or two-way, two-phase four-wire stepper motor, which is very suitable for precise control needs.

  The corresponding interface can be directly connected to peripherals such as steering gear and infrared obstacle avoidance. 

At the same time, there is a charger interface, flip up the switch, and enter the charger to charge the rechargeable battery. 

Very convenient! This four-channel DC motor drive module adopts the original brand new L293D chip of ST Company,

adopts SMT process with high stability, and uses high-quality aluminum electrolytic capacitors to make the circuit work stably. 

It can directly drive 4 3-16V DC motors, and provides a 5V output interface (the minimum input is only 6V ),

it can supply power to the 5V single-chip circuit system (low ripple coefficient) , 

supports 3.3V MCU ARM control, and can be easily controlled DC motor speed and direction can also control 2- phase stepper motor

and 5- wire 4- phase stepper motor. It is a 4-wheel car, an essential tool for smart cars.

One of the control direct value tables, and the other three analogy.
