2 PCS Motor Drive Expansion Board L293D ESP12 DEV KIT Development Board(HW-588A)
1. lESP12 DEV KIT development board expansion module
2. Lead out all function pins of ESP12 DEV KIT: SPI, UART, GPIO, AI and 3.3V power interface
3. Extend two-way motor drive, which can directly drive two-way motor
4. Onboard power switch
5. Separate motor power supply and control power supply; in the experiment, the short-circuit block can be combined to short-circuit VIN and VM, and supply power to the motor and control board at the same time
6. 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
7. Working temperature: -25 to 125 degrees Celsius
8. Power dissipation: 4w
9. Output voltage: 4.5V~9V, can be powered separately
10. Input voltage: 4.5V~36V, can be powered separately
11. Drive form: dual-channel high-power H-bridge drive
12. 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
