ESP-12E motor drive expansion board

Introduction:

Development of the first motor driven expansion board based on ESP-12E.

Characteristic:

L ESP12 DEV KIT development board expansion module;

L leads to all function pins of ESP12 DEV KIT: SPI, UART, GPIO, AI and 3.3V power interface.

L extends two motor drives, which can directly drive two motors.

L on-board power switch;

L L293D

L motor power range: 4.5V~36V;

L control power range: 4.5V~9V;

In the experiment, VIN and VM can be shortened by combining short circuit blocks, and the power supply for motor and control board can be provided simultaneously.

Product specification

Power input:

The motor power supply (VM): 4.5V to 36V, can be powered separately.

Controlled power supply (VIN): 4.5V to 9V (10VMAX), which can be powered separately.

65

The logical working current is Iss: ≤60mA(Vi=L),≤22mA(Vi=H)

The working current of driving part is Io: ≤1.2A

Maximum dissipation power: 4W (T=90 C)

Control signal input level: high level: 2.3V≤VIH≤VIN; low level: –0.3V≤VIL≤1.5V

Working temperature: -25 C ~ + 12 5 C

Driving form: two way high power H bridge drive

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

Module weight: About 20g

Matters needing attention

When l is inserted into the ESP-12E module, please note that the antenna direction is consistent with the direction of the expansion board.

L uses short circuit module to supply power to control board and motor simultaneously.
