NodeMcu Lua Base Board ESP12E

NodeMcu ESP12E Lua Base Board 

The L293D Motor Driver module is designed to work seamlessly with both the ESP12E Dev Kit and NodeMCU. This shield board utilizes the high-performance L293DD full-bridge chip, allowing for direct control of 2-channels of DC motors or one-channel of a stepper motor.

This motor shield board utilizes the IO port of ESP-12E Dev Kit as a control port, thanks to the logic chip inside which enables IC driving. As a result, the board offers four ports: D1, D2, D3, and D3, designated for PWMA (motor A), PWMB (motor B), DA (direction of motor A), and DB (direction of motor B) respectively. Additionally, it boasts numerous pins such as VIN, 3.3V, DIO, AIO, SDIO, UART, SPI,RST,and EN for convenient connection with various sensors including temperature and humidity sensors,different types of alarms (e.g., buzzer), light sensors,and relay sensors.

Characteristics of NodeMcu ESP12E Lua Base Board:

• The expansion module for the ESP12 DEV KIT development board.
• The ESP12 DEV KIT includes a variety of pins, such as SPI, UART, GPIO, AI, and a 3.3V power connector.
• Prolong the dual-functionality of the motor by utilizing both two-way motor-driven and two-way direct-drive features.
• The power switch located onboard.
• The separation of motor power and control power.
