Description:

• ESP8266 WiFi Motor Drive Expansion Board, L293D ESP12E Lua Things Smart Car

• This is the first motor shield for ESP8266 based on ESP-12E. It is very convenientand cheap to diy a WiFi RC smart car. In our shop, we also develop a WiFi smartcar, which can be controlled by mobile, PC, and wechat (now just in China).
• 
  Parameters:

• Name: ESP-12E 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;

• driven chip: L293D;

• voltage for motor: 4.5V-36V;

• voltage for ESP control board: 4.5V-9V;

• 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 andmotor.

• Development of NodeMCU based on the ESP-12E , fully compatible with the existing version.
