CSR8645 software version introduction:

1 . Buttons: There are 6 function buttons: POWER-EN, PLAY, VOL +, VOL one, PREV, NEXT
The key functions are introduced as follows:
POWER-EN: When the switch is used to control the switch of the module, through the toggle switch, when the
POWER-EN is connected to the BAT, the module is turned on; when the POWER-EN is disconnected from the BAT,
the module is shut down, usually used when battery power is supplied. When the module is powered on, you only
need to connect the POWER-EN in series with a 10K resistor to BAT to power on the module, which is usually used
when external power is supplied.
