Can you provide a code using python 3 for the product, please?

The documentation on your website and product wiki has no wiring diagram to motors and power supply. The power supply is supposed to be 7-12 V for the board but when board is powered from external power supply source it is also sending power to Raspberry Pi. So the questions you need to correctly answer and document are:

1. Can we connect two power supplies one to this motor driver board 7-12 V and another for Raspberry Pi at the same time?
2. If we connect the external power supply to the board and it sends higher voltage to Raspberry Pi will it damage Raspberry Pi or does it have voltage regulator to step down to the voltage the RPi needs?
3. When we connect two power supplies one for the motor driver and another for RPi, will the board automatically NOT send the power to RPi and only send power to motors?

Please answer these questions properly as it is very risky without knowing this whether the Raspberry Pi or the board will be damaged especially when Raspberry Pis are not that easily available to order and they cost a lot more than the motor driver board.

Is it possible to change the I2C address of the board?
