ESP-12E Motor Drive Expansion Board
Introduction:
The first 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;
Expansion of two motor drives, capable of directly driving 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, short circuit blocks can be combined to short circuit VIN and VM, while supplying power to the motor and control board.
Product technical specifications
Power input:
~Motor power supply (VM): 4.5V~36V, can be powered separately;
~Control power supply (VIN): 4.5V~9V (10VMAX), can be powered separately;
~The module provides short circuits (short circuit VM and VIN), which can easily use a single power supply (must be 4.5V~9V) to drive and control the motor simultaneously;
Logic working current Iss: ≤ 60mA (Vi=L), ≤ 22mA (Vi=H);
Operating current Io of the driving part: ≤ 1.2A;
Maximum dissipation 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 ensure that the antenna direction is consistent with the expansion board direction;
By using short-circuit modules, power can be supplied to both the control board and the motor simultaneously.
