Note:

Audio output module for differential output, can not be directly connected with an amplifier, the circuit needs into the nondifferential signal, of course, if amplifier support can be directly connected with an amplifier IC.
The module of the software has two kinds, one kind is the key to boot, suitable for battery-powered occasions; one is electrically powered, adapted to the ordinary power supply occasions to use the kind of software, please note.
The module requires knowledge of iron welding technology and electronic technique, if does not have this condition, is likely to be a good module to your hand will become a waste, please take caution.
A voltage of IO the highest resistance to 1.8V module only, more than 1.8V burning module may, please note.
Bluetooth modules are very sensitive to static and electric leakage, please use the constant temperature soldering iron.
