Motor Shield Board L293D for ESP-12E from ESP8266 esp 12E kit diy rc toy wifi rc smart car remote control
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.
 
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: 2.3VVIHVIN; Low: -0.3VVIL1.5V
 
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)
 
Module Weight: about 20g
Precautions
 
When l insert ESP-12E module, please note the direction consistent with an expansion board antenna;
 
l use of short modules that can simultaneously control board and motor.
