ESP8266 + motor shield


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)

Module Weight: about 20g
