Specification

Description

The L293D motor driver board is a commonly used motor driver module that is compatible with various microcontrollers, including the ESP8266 WiFi NodeMcu Lua ESP12E development board. It is used to control DC motors or stepper motors in various projects.

In this motor shield board, the IO port of the ESP-12E Dev Kit is used as the control port. The logic chip configured inside can finish IC driven. Thus, the shield board has four ports: D1, D2, D3, and D3, which are used as PWMA(motor A), PWMB (motor B), DA (direction of motor A), and DB (direction of motor B), respectively. In addition, this shield board has many pins, such as VIN, 3.3V, DIO, AIO, SDIO, UART, SPI, RST, and EN, thus can conveniently connect all kinds of sensors (e.g., temperature and humidity, buzzer, light, relay sensor, etc.)

Details about the L293D motor driver board and its use with the ESP8266 NodeMcu:

Motor Driver IC: The L293D motor driver board is built around the L293D IC, which is designed to control two DC motors in either forward or reverse direction. It can also control a single stepper motor.

Voltage Compatibility: The L293D motor driver board typically operates at a logic voltage level of 5V, which is compatible with many microcontrollers like the ESP8266 NodeMcu. The board can also handle higher motor supply voltages, which vary depending on the specific L293D IC used.

Motor Channels: This module provides two motor channels, often labeled as "Motor A" and "Motor B." Each channel can control one DC motor. For stepper motor control, both channels can be used in tandem.

Direction Control: You can control the direction of each DC motor by toggling the input pins for each channel. By changing the logic levels on these pins, you can make the motors rotate forward or backward.

PWM Control: If you want to control the speed of DC motors, you can use Pulse Width Modulation (PWM) signals from the ESP8266 NodeMcu to control the enable pins on the motor driver board. This allows you to vary the motor speed by adjusting the duty cycle of the PWM signal.

Input Pins: You will typically need to connect four GPIO pins from the ESP8266 NodeMcu to control the direction and speed of the two motors. Each motor has an input pin for direction and another for speed control.

Power Supply Pins: The motor driver board will require a separate power supply for the motors, typically in the range of 4.5V to 36V, depending on the specific L293D IC used. It's essential to provide the appropriate voltage for your motors.

Applications:

The L293D motor driver board is commonly used in robotics, automation, and DIY projects where DC motor control is needed. It's a versatile choice for controlling motors with microcontrollers like the ESP8266 NodeMcu.
