The high power Bluetooth amplifier board is a cost-effective solution that provides 100W of output power and features a volume control button, Bluetooth 5.0 input, and dual-track output. It can be powered by a DC voltage of 5~24V and is compatible with 4-8Ω passive speakers with a power rating of 50W-300W. You can use this board with Raspberry Pi, mobile phones, and other main controllers with Bluetooth to create your own projects. The board is equipped with four 470uf capacitors for stable output and includes a heat sink and an excellent power module that allows it to operate smoothly for an extended period of time under high output conditions. It also comes with bottom/top protective panels and has auto overheat and short circuit protection.
Operating Instruction
Connect the board with a speaker, power it on. Rotate the knob then the indicator led light 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.
Note:
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.
