Features
ESP12 DEV KIT development board expansion module;
Leads all function pins of ESP12 DEV KIT:SPI, UART, GPIO, AI and 3.3V power interface;
Expand two-way motor drive to directly drive two motors;
Onboard power switch;
L293D
Motor power supply range:4.5V~36V;
Control power supply range:4.5V~9V;
Motor power supply and control power supply are separated. In the experiment, VIN and VM can be short-circuited by short-circuit block combination, and the motor and control board can be supplied with power.
specifications
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 circuit (short circuit VM and VIN), which can conveniently use one power supply (must be 4.5V ~ 9V) to complete the drive and control of the motor at the same time;
Logical operating current Iss:60mA (Vi = L), 22mA (Vi = H);
Driving part operating current Io:1.2A;
Maximum power dissipation:4W (T=90C)
Control signal input level:high level:2.3V VIH VIN; low level:-0.3V VIL 1.5V
Working temperature:-25 C ~ +125 C
Drive form:dual high power H-bridge drive
ESP12E Dev Kit control port:D1, D3 (A motor); D2, D4 (B motor)
Module weight:about 20g
Note
When inserting an ESP-12E module, pay attention to the direction of the antenna and the direction of the expansion board;
With the shorting module, the control board and the motor can be powered simultaneously;
