This is for both the NodeMCU Development board and the L293D motor controller dev board / shield.
The board breaks out all the pins of the NodeMCU dev board.
Motor shield for ESP-12N
This is the first motor shield for ESP8266 based on ESP-12N
It is very convenient and cheap to DIY a WiFi RC smart car or any type of robotics or UAV platform.
l ESP-12Notor 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
