Grove Motor Driver (TB6612FNG) bis

A side question regarding this board :
Documentaion mentions I2C address is configurable (0x01 - 0x7F)
But I don’t see any explanation concerning that possibility (h/w, s/w ?)
Would appreciate information on that point.

Only the internal firmware can be configured.We did not open the interface to users, and the documentation was somewhat misleading.I’ll fix it right away.
