Attention
► 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.
► For your safety, be sure to use a regular lithium-ion battery with charging
protection.
► Please use a stable power supply such as 3.7V-5V lithium battery or 5V power
adapter. Do not use disposable batteries, power bank, multi-function
transformers and other power supply with unstable voltage and current.
► The antenna should be far away from metal materials so as not to affect the
transmission distance.
