Operation Instruction

Connect the board with a speaker, power it on. Rotate the knob then the indicator led lights up. Turn on the Bluetooth of your phone or Raspberry Pi, the” BT-WUZHI” will be searched, and then click to connect it. It connects successfully with a prompt tone, and now it can play music. The Bluetooth will be reconnected automatically when the module is powered on next time.


The board will output adequate power only when the audio input and power source voltage/current are sufficient. The higher the power supply voltage, the larger the output power. Besides that, speaker impedance also changes the amplifier board power output. Please note that in the case of enough voltage and current, the larger the speaker impedance in ohms, the smaller the output power.
