Hi,

A motor shield for Wemos is already supported. Please, check if the driver added in #7764 works for you. Thanks.

The code of the old version V1(https://github.com/wemos/WEMOS_Motor_Shield_Arduino_Library) and the new version (https://github.com/wemos/LOLIN_I2C_MOTOR_Library) are very different.

The driver added in #7764 is not working with new version.

Please add a support for new version.

Thanks

Please, use the libraries already included in Tasmota that are tuned to use less RAM and FLASH. Thanks.

Hi Ascillato

I bought the lollin V2 motor drivers but i can't make it work with tasmota.

I took the correct bin (sensors), configure SDA and SCL.
I can detect the motor drivers at 0x30 with I2Cscan but how could i use it ?

I really apreciate if you could help me to make it work.

regards
