L293D Wifi Motor Drive Sheild Module for Android NodeMcu Lua ESP-12E ESP8266
Name: nodemcu motor shield
using ESP-12 DEV KIT development shield module
extend the output ports for ESP-12 DEVKIT: SPI, UART, GPIO, AI and 3.3V power interface
extend 2-ways motor, then can directly drive 2-ways motor
design a power switch
voltage for motor: 4.5V-36V
voltage for ESP control board: 4.5V-9V
driven cihip: L293D
disparate the power of ESP board andmotor for avoiding the interference. In our experiments, for convenience, a shortcut module is used to connect VIN and VM for the power of ESP board and motor.

Feature:
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 ℃)
Control signal input level: High: 2.3V≤VIH≤VIN; Low: -0.3V≤VIL≤1.5V
Working temperature: -25 ℃ ~ + 125 ℃
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,
