Is my motor driver broken??

I tried to use TB6612FNG and nodemcu esp8266 to control the motor through my phone(Wifi).
I am sure the nodemcu esp8266 can work, output power for INA1/INA2(control by my phone).(I've test by LED).and my motor is fine.

Here is my circuit diagram:
Circuit diagram

If there is no problem in this circuit diagram,I suspect my motor was broken.
But how can I test the motor driver??I can't find the circuit diagram of this motor driver.(I only found this but it's different from mine)

If you need, the attachment is my program.
Thank you for any help you can provide.
