Geekcreit® TDA7492P 50W+50W Wireless Bluetooth 4.0 Audio Digital Amplifier Board (10003121)
TDA7492P digital amplifier chip, designed to optimize the circuit layout, the sound quality is very good, big power.
DIP switches can be more easily directly adjusted after-class amplifier gain,to better promote the impedance larger speakers.
If you directly use Bluetooth, when power, wait 3s~10s, until led Blue and Red light flashing alternately, then you can use your device to find my Bluetooth module, you will find "SANWU Audio", then connect it, can directly use it. Remember back to even.
