ESP-12E motor drive expansion board Description: Based on the first motor-driven expansion board ESP-12E development. 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. Technical Specifications Power input: – Motor Power (VM): 4.5V ~ 36V, can be a separate power supply; ~ Control power (VIN): 4.5V ~ 9V (10VMAX), can be powered separately; ~ Module provides short-circuit sub (short the VM and VIN), you can easily use one power (must 4.5V ~ 9V) simultaneously drive and control the motor; Logic Operating current Iss: =60mA (Vi = L), =22mA (Vi = H); Drive part of the work current Io: =1.2A; Maximum power dissipation: 4W (T = 90 ) Control signal input level: High: 2.3V=VIH=VIN; Low: -0.3V=VIL=1.5V Working temperature: -25 ~ + 125 Drive Type: Dual high-power H-bridge driver ESP12E Dev Kit Control Port: D1, D3 (A motor); D2, D4 (B motor) Package Included: 1 x L293D Wifi Motor Drive Shield Module For Arduino NodeMcu Lua ESP8266 ESP-12E
