Description
This is the first motor-driven expansion board that based on ESP- 12E development platform. When inserting ESP-12E module, please note the direction consistent with an expansion board antenna; The use of short modules that can simultaneously control board and motor.
Features
- ESP12 DEV KIT development board expansion module;
- lead ESP12 DEV KIT all the features of pins: SPI, UART, GPIO, AI and 3.3V power connector;
- extend two-way motor-driven, two-way direct drive motor;
- onboard power switch;
- L293D
- Motor power, control power separation; In the experiment, a short circuit can block the merger, shorted to VIN and VM, while power supply to the motor and the control board.
