ESP8266 WiFi Motor Drive Expansion Board

Introduction:

A motor drive expansion board developed based on ESP-12E.

Features:

ESP12 DEV KIT development board extension module;

Lead out all functional pins of ESP12 DEV KIT: SPI, UART, GPIO, AI, and 3.3V power interface;

Expanding two motor drives to directly drive two motors;

On board power switch;

L293D

Motor power supply range: 4.5V~36V;

Control power supply range: 4.5V~9V;

Separation of motor power supply and control power supply; In the experiment, the VIN and VM can be short circuited by merging short-circuit blocks, while supplying power to the motor and control board.

Product technical specifications:

Power input:

~Motor power supply (VM): 4.5V~36V, can be supplied separately;

~Control power supply (VIN): 4.5V~9V (10VMAX), can be powered separately;

~The module provides short circuit components (short circuit VM and VIN), which can conveniently use one power supply (must be 4.5V~9V) to complete motor drive and control simultaneously;

Logic working current Iss: ≤ 60mA (Vi=L), ≤ 22mA (Vi=H);

Operating current Io of the driving part: ≤ 1.2A;

Dissipated power: 4W (T=90 ℃)

Control signal input level: High level: 2.3V ≤ VIH ≤ VIN; Low level: -0.3V ≤ VIL ≤ 1.5V

Working temperature: -25 ℃~+125 ℃

Drive form: dual high-power H-bridge drive

ESP12E Dev Kit control ports: D1, D3 (A motor); D2, D4 (B motor)

Module weight: approximately 20g

Matters needing attention:

When inserting the ESP-12E module, please note that the antenna direction is consistent with the expansion board direction;

By utilizing a short circuit module, power can be supplied to both the control board and the motor simultaneously.
