NameESP-12E motor shield
Voltage for motor4.5V to 36V
Voltage for ESP control board4.5V to 9V
Driver chipL293D

1. ESP12E Motor Shield is a high-current motor drive module compatible with ESP12E Dev Kit and . The module is designed with a plug-in board and can be directly connected to the ESP12E Dev Kit or NodeMCU Lua module.

2. The module adopts the excellent high-power motor dedicated full-bridge chip L293DD produced by STMicroelectronics. It can directly drive 2 DC motors or 1 stepping motor, and the driving current can reach 1.2A. The layout of the circuit diagram is reasonable, the package is packaged and the installation is very convenient.

3. The module uses the IO port of the ESP12E Dev Kit as the control port, and the internal logic chip completes the motor IC drive. Therefore, it only occupies four ports of the control boards D1, D2, D3, and D4, which are respectively used as PWMA (motor A speed) and PWMB (motor B). Speed), DA (Motor A direction), DB (Motor B direction) function.

4. The module also draws multiple pins such as VIN, 3.3V, DIO, AIO, SDIO, UART, SPI, RST, EN, etc., which can be easily connected to various sensors (temperature and humidity, buzzer, illumination, relay, etc.).

5. The module adopts a user-friendly design scheme, and the power button switch allows the user to conveniently switch the power.

6. This module can be used directly to control smart cars.
