Description:
L293D motor driver shield is one of the most widely used shields for driving the motor, which also has the ability to control via Wi-Fi, and by adding a Wi-Fi control board on the driver shield, you can make the motors control smarter. On this board, you can install the ESP8266 12E Wi-Fi shield module and control the DC motor up to 36 volts using WIFI. This shield is a Node MCU pin expander that has a UART and SPI interface as well as 3 GPIO rows and an analog interface.
Feeding the motors and feeding the shield are defined separately, and by connecting these two feedings together, feeding the motor and the shield can be done simultaneously.
The shield board has four ports D1, D2, D3 and D3, which are used as PWMA (motor A), PWMB (motor B), DA (motor direction A) and DB (motor direction B). , Respectively. In addition, this protection board has many pins such as VIN, 3.3V, DIO, AIO, SDIO, UART, SPI, RST and EN, so it can easily connect a variety of sensors (such as temperature and humidity, alarm, light, alarm ) to connect.
