PAM8406 BT 5.0 DIY Kit Linear Audio Power Amplifier Board DC3.7-5V Stereo Audio XY-P5W
Operation Specification
Supply the module - the blue LED turns on and enters BT mode. After playing the audio tone, it waits for pairing. Turn on phone Bluetooth and search for "XY-P5W". Click "XY-P5W" to connect to the board. Connection is confirmed with an audio tone. After successful connection, you can play music. The amplifier board prepares for next pairing with an audio tone when Bluetooth is disconnected.
Lithium Battery Usage Precautions
When using battery power, the decoding board automatically shuts down when battery voltage drops below 3.3V. Requires power cycle or full charge, then short circuit the on/off contact for 2 seconds to resume normal operation.
When battery voltage is too low, "Zizi" noise may occur. In this case, the battery needs charging.
No lithium battery charging protection circuit is designed on the decoding board. Recommended to use lithium batteries with built-in protection boards.
If your charging battery supports micro USB direct charging, you can use micro USB to charge the battery directly.
Power supply must be more than 10W. Recommended to use power supply of more than 20W. Insufficient power supply will affect sound quality.
