Giới thiệu Bảng Mạch Mở Rộng Động Cơ Esp8266 Wifi Esp12E tại Lotte Market

Introduction:
The first motor - driven expansion board based on esp - 12e was developed.
Characteristics:
L esp12 dev kit development board extension module;
L leads esp12 dev kit to all functional pins: spi, uart, gpio, ai and 3.3v power sockets;
L-extension two-way motor drive, can directly drive two-way motor;
L-board power switch;
L l293d
L motor power range: 4.5v~36v;
L control power supply range: 4.5v~9v;
L motor power supply, control power separation; in experiments, vin and vm can be combined by short circuit block, and the motor and control board can be supplied with electricity.
Technical specifications of products

Power input:
~motor power supply (vm): 4.5v~36v, can be supplied separately;
~control power supply (vin): 4.5v~9v (10vmax), with separate power supply;
~the module provides short circuit (short circuit vm and vin), which can be easily used by all-way power supply (must be 4.5v~9v) simultaneously to complete the motor drive and control;
Logical working current iss: 60ma (vi = l), 22ma (vi = h);
Io: 1.2a driving part of the working current;
Maximum dissipation power: 4w (t = 90)°C)
Control signal input level: high level: 2.3 v vih vin; low level: - 0.3 v vil 1.5 v
Working temperature: - 25°C~+ 125°C
Driving form: double-circuit high power h bridge drive
Esp12e dev kit control port: d1, d3 (a motor); d2, d4 (b motor)
Module weight: about 20g
Points to note
When inserting the esp-12e module, note that the antenna direction is consistent with that of the expansion board;
L using short-docking module, can supply both the control board and the motor.
