Re: WeMos D1 Mini Motor Drive Shield (HCWEMO0010)

I have given up on original and tried use TB6612FNG. Because I wanted my car to be small, I used 3.7v lipo's ( 2 for TB6612fng and 1 for wemos + common ground) But it worked sometimes, and made squeaking noise. So thought it is because of low battery power. It now doesnt spin. Is 3v3 pin output only...

Thanks
I did a tweak. I soldered to Pin3 (left side 3rd from top) on the microcontroller , after looking at the pin diagram.

Can this be used with Arduino ? If yes, how to get SQW ? I need SQW to wake up arduino from sleep. please advice

Re: WeMos D1 Mini Motor Drive Shield (HCWEMO0010)

No you will need to supply 3.3V power via the 3V3 and GND pins to power the module. Note that all the information I have given is for the version of the module we sell. But I thought the driver shield will block 3v3 pin too. [ not sure , if I have to use long header pins] If I stack driver on top o...

Re: WeMos D1 Mini Motor Drive Shield (HCWEMO0010)

Thank you @andrew I don't understand why a motor driver should be so complicated. It needs new firmware, RTS and 3V pins connected for a special setting, and no clue on what pins are used between wemos d1 and the driver shield. Will the driver supply power to wemos d1? or both need seperate power in...

Re: WeMos D1 Mini Motor Drive Shield (HCWEMO0010)

I thought control pins only send voltage, and if 5v is suppied to some driver pins [ I don't know which ones] , the motor should spin.
Can Arduino uno be used to test the motor driver?

Re: WeMos D1 Mini Motor Drive Shield (HCWEMO0010)

I would like to test the driver using a motor and battery. Is that possible?
Reason - test each component individually, and next integrate with Wemos D1 mini
