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