Grove - I2C Motor Driver V1.3 is killing i2c communication

Hello,

I have a brand new Grove - I2C Motor Driver V1.3 + Grove Base Hat for Raspberry Pi.

When connecting the Motor driver to i2c of the base hat it immediately jams all i2c communication: all i2c devices that are perfectly running before stop working when the motor driver is attached. In addition “i2cdetect” runs slowly and doesn’t find any i2c device (before attaching the motor driver “i2cdetect” detects the other i2c devices).

Even if the motor driver is the only attached i2c device “i2cdetect” runs slowly and doesn’t find any i2c device.

In addition all 4 trning direction leds (2 x red, 2 x green) on the motor driver are always on as soon as power is attached. Resetting the device is not helping.

Any ideas what could be wrong?

Thanks, best regards,
Stephen
