This is just the LM293D dev board/shield that your NODEMCU dev board plugs into.
The pictures are examples of how it will look when you fit your NodeMCU to the board.
The board breaks out all the pins of the NodeMCU dev board.
Motor shield for ESP-12E
This is the first motor shield for ESP8266 based on ESP-12E.
It is very convenient and cheap to DIY a WiFi RC smart car or any type of robotics or UAV platform.
l ESP-12E motor shield - uses the NODEMCU Development Board to power the Driver
l using ESP-12 DEV KIT development shield module
l extend the output ports for ESP-12 DEVKIT: SPI, UART, GPIO, AI and 3.3V power interface
l drive two motors at once
l design a power switch
l driver chip: L293D
l voltage for motor: 4.5V-36V
l voltage for ESP control board: 4.5V-9V
l a jumper is used to connect VIN and VM for the power supply of ESP board and motor to minimise interference
