High Power Bluetooth Power Amplifier Audio Board

High Power Bluetooth Stereo Amplifier Board With 100W Dual Channel Audio Output
The High Power Bluetooth Power Amplifier Board is a compact and powerful wireless audio amplification solution designed for DIY speaker systems, multimedia audio projects, and smart audio applications. Featuring Bluetooth 5.0 wireless connectivity and dual-channel stereo amplification, the board delivers up to 100W x 2 output power, enabling high-quality audio playback for a wide range of passive speaker configurations. The integrated volume control knob provides convenient adjustment, while the compact design simplifies integration into custom audio systems.
Designed for stable and reliable operation, the amplifier supports a wide 5V to 24V DC input range and can drive 4 to 8 passive speakers rated from 50W to 300W. Four onboard 470F capacitors ensure stable power delivery during high-output operation, while the integrated heatsink enhances thermal performance. Automatic overheat and short-circuit protection improve safety and long-term reliability. Acrylic protective panels further protect the circuitry, making the board suitable for portable speakers, smart home audio devices, multimedia terminals, and Raspberry Pi-based audio projects.

High Power Bluetooth Power Amplifier Board (100W2)

Operating Instruction

Connect the board with a speaker, and 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.

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.
