Introduction:

Motor drive expansion board based on ESP-12E.

Features:

1. ESP12 DEV KIT development board expansion module;

2. Lead out all function settings of ESP12 DEV KIT: SPI, UART, GPIO, AI and 3.3V power interface;

3. Expand two-way motor drive, which can directly drive two-way motor;

4. Onboard power switch;

5. L293D

6. Motor power range: 4.5V~36V;

7. Control power supply range: 4.5V~9V;

8. Motor power supply and control power supply are separated; in the experiment, the short-circuit block

can be combined to short-circuit VIN and VM, and power the motor and control board at the same time.

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 a short circuit (short-circuit VM and VIN), you can easily use a power supply (must

be 4.5V ~ 9V) at the same time to complete the drive and control of the motor;

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

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

Power dissipation: 4W (T = 90℃)

Control signal input attenuation: high attenuation: 2.3V≤VIH≤VIN; continuous: -0.3V≤VIL≤1.5V

Working temperature: -25℃～＋125℃

Drive form: dual high-power H-bridge drive

ESP12E development board control port: D1, D3 (A motor); D2, D4 (B motor)

Module weight: about 20g

Precautions

1. When inserting the ESP-12E module, please note that the antenna direction is consistent with the

direction of the expansion board;

2. Using the short-circuit module, the control board and the motor can be powered at the same time.
