The Bluetooth audio receiver board already has dual 5W power amplifier circuit. It doesn't need to connect with extra power amplifier. The output of dual amplifiers can not be connected in parallel or connected to the negative electrode, otherwise the power amplifier chip will be damaged.

2-8 ohm and 3-10W speakers are compatible with the receiver board, but 3 ohm&5W or 4 ohm&10W are recommended. It outputs stereo. It also supports USB sound card, without drive. Just plug and play (in normal lithium battery power supply situation).

Maximum working current 5V 2A. Better sound quality when you use 5V 2A or more voltage power supply. We suggest using 3.7-5V lithium battery. (the lithium battery should have charging protection!) The on-board USB interface can not only be used to USB sound card but also charge the lithium battery and also used as a 5V power supply port. But you should note that do not use the power supply with unstable voltage and current, such as dry battery, portable charger, multi-function transformer and so on.
【Please Note】We recommend you to use 3.7V lithium battery as power supply to reduce signal interference and noise (The lithium battery should have charging protection!). Do not use dry batteries, power bank, multi-function transformers and other unstable power supply. Do not get close to metal parts because metal parts will interfere the module.
