ΣΗΜΕΙΩΣΕΙΣ

When this module is powered from a computer via micro USB, it is only possible to play audio from the computer, and it is not possible to connect with Bluetooth. For the Bluetooth function, use a wall socket adapter or a USB cable that can not transfer data.
The board also contains a "VBAT" pin to which a 3.7V Li-ion/Li-Po battery could be connected, however we do not recommend this due to the lack of a suitable charging circuit.
