The seller has indicated that they will usually have this item
ready to ship within 15 business days. Shipping time depends on your delivery address. The most
accurate delivery time will be calculated at checkout, but in
general, the following shipping times apply:
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
