ESP8266 + motor shield
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: 2.3V≤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
