ESP-12E motor drive expansion board
Introduction:
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 the features of pins: SPI, UART, GPIO, AI and 3.3V power connector;
l extend two-way motor-driven, two-way direct drive motor;
l onboard power switch;
l L293D
l Motor Power Range: 4.5V ~ 36V;
l control supply range: 4.5V ~ 9V;
l Motor power, control power separation; In the experiment, a short circuit can block the merger, shorted to VIN and VM, and the motor control board and power supply.
