About this product
*ESP12E Motor shields is a compatible ESP12E Dev Kit and NodeMCU a large current motor driver module. The module adopts foldable plug-in circuit design, can directly access ESP12E Dev Kit or NodeMCU Lua module.
*DC motor can be directly driven 2 road or 1 stepping motor road, the largest drive current can reach 1.2A. Wiring diagram layout is reasonable, SMD encapsulation, installation is very convenient.
*The module at the same time leads to VIN, 3.3V, DIO, AIO, SDIO, UART, SPI, RST, EN and many more pins, you can easily access various sensors (temperature and humidity, buzzer, lighting, relay, etc. )
*USES ESP12E Dev Kit module I / O mouth as control port, IC internal configuration IC of the complete motor drive chip, then just take the panel D1, D2, D3, D4 four ports, respectively as PWMA (motor speed A), PWMB (motor speed B), DA (motor direction), DB (motor direction B) of the function.
*Module USES humanized design, use the power button switch, users can conveniently on the power switch.
