ESP-12E motor drive expansion board Description:  Based on the first motor-driven expansion board ESP-12E development. Features: l ESP12 DEV KIT development board expansion module; l lead ESP12 DEV KIT All-function pins: SPI, UART, GPIO, AI and 3.3V power connector; l expand two-way motor-driven, two-way direct drive motor; l onboard power switch; l L293D l Motor power range: 4.5V ~ 36V; l Control power range: 4.5V ~ 9V; l Motor power, control power separation; In the experiment, by short-circuiting block the merger, the VIN and VM short, while power supply to the motor and the control board.  1.This is a breadboard for the LOLIN NodeMCU Development Board ESP8266-12E for Arduino IDE see other listing 2.Please note this has a pin spacing of 28MM between the rows unlike the unit made by DOIT witch is 23 MM 3.This is compatible with the LOLIN NodeMCU not the DOIT device
