DollaTek ESP8266 ESP-12E CP2102 Development Board and L293D Wifi Motor Drive Expansion Board Shield Module for Arduino

• ESP12E Motor shields is a compatible ESP12E Dev Kit and NodeMCU a large current Motor driver module. Module adopts fold plug-in circuit board design, can be directly access ESP12E Dev Kit
• dc motor can be driven directly 2 road or road 1 stepper motor, drive current biggest can reach 1.2 A. Circuit diagram layout is reasonable, SMD encapsulation, installation is very convenient.
• Module at the same time lead to VIN, 3.3 V, DIO, AIO, SDIO, UART, SPI, RST, EN, and many other pins, you can easily access various sensors (temperature and humidity, buzzer, lighting, relay, etc.)
• Module USES ESP12E Dev Kit IO mouth as control port,Internal configuration logic chip IC complete motor drive, so just take up panel D1, D2, D3, D4 four ports, respectively as PWMA (A motor speed), PWMB (B motor speed), DA (A motor direction ), DB (B motor direction) of function.
• Module USES the humanized design, use the power button switch, users can conveniently on the power switch.

DollaTek trademark Reg.NO:013726393 Features: ESP12 DEV KIT development board expansion module; Lead ESP12 DEV KIT All-function pins: SPI, UART, GPIO, AI and 3.3V power connector; Expand two-way motor-driven, two-way direct drive motor; Onboard power switch; Motor power range: 4.5V ~ 36V; Control power range: 4.5V ~ 9V; Motor power, control power separation; In the experiment, by short-circuiting block the merger, the VIN and VM short, while power supply to the motor and the control board. Precautions: When insert ESP-12E module, please note the direction consistent with an expansion board antenna; Use of short modules that can simultaneously control board and motor. Packing List: 1x ESP-12E expansion board 1x NodeMCU
