4. If the battery is properly connected, the OpenMV LED will blink white at the start. In addition to that, a debugging feature was added such that the OpenMV LED will be red once it is switched on. Everytime a function is called, it will blink green for the period of the function.
3. In addition to that, since OpenMV is not a stackable feather component, you need to add pull up resistors for both the SDA and SCL lines. The way to do this is by connecting two 2.2kOhms resistors where one end is connected to ESP32 3V and the other one is connected to the SDA and SCL respectively.
