ESP8266 L293D Motor Driver Expansion Board WiFi NodeMcu Lua ESP12E V2.0


L293D Motor Driver module is compatible with ESP12E Dev Kit and NodeMCU. This shield board is driven by the power full-bridge chip L293D which can directly drive 2-channels DC motors or one-channel stepper motor.


In this motor shield board, the IO port of ESP-12E Dev Kit is used as the control port. The logic chip configured inside can finish IC driven. Thus, the shield board has four ports: D1, D2, D3, and D3, which are used as PWMA(motor A), PWMB (motor B), DA (direction of motor A), and DB (direction of motor B), respectively. In addition, this shield board has many pins, such as VIN, 3.3V, DIO, AIO, SDIO, UART, SPI, RST, and EN, thus can conveniently connect all kinds of sensors (e.g., temperature and humidity, buzzer, light, relay sensor, etc.)


Features:
ESP12 DEV KIT development board expansion module
Lead ESP12 DEV KIT all the features of pins: SPI, UART, GPIO, AI, and 3.3V power connector
Extend two-way motor-driven, two-way direct-drive motor
onboard power switch
Motor power, control power separation


Motor power supply (VM): 4.5V ~ 36V, can be powered separately
Control power (VIN): 4.5V ~ 9V (10VMAX), can be powered separately
Module provides short-circuit sub (short the VM and VIN), you can easily use one power (must 4.5V ~ 9V) while completing motor drive and control
Logic Operating current Iss: =60mA (Vi = L), =22mA (Vi = H)
Drive part of the work current Io: =1.2A
Maximum power dissipation: 4W (T = 90 °C)
Control signal input level: High: 2.3V=VIH=VIN; Low: -0.3V=VIL=1.5V
Working temperature: -25  °C~ + 125  °C
Drive Type: Dual high-power H-bridge driver
ESP12E Dev Kit Control Port: D1, D3 (A motor); D2, D4 (B motor)
Expand two-way motor-driven, two-way direct drive motor
Onboard power switch
Motor power, control power separation; In the experiment, by short-circuiting block the merger, the VIN and VM short, while power to the motor and the control board
