High Power Bluetooth Power Amplifier Board

High Power Bluetooth Power Amplifier Board (100W×2) enables rapid development of custom wireless speaker systems and compact stereo audio projects. This high‑output Bluetooth amplifier module integrates Bluetooth 5.0 wireless audio input, dual‑channel stereo output, and a physical volume control knob on a compact board. Operating from a wide 5–24V DC supply, the audio amplification board supports 4–8Ω passive speakers rated between 50W and 300W. Wireless music streaming can be paired directly with mobile devices or embedded computers such as Raspberry Pi, making the module suitable for DIY speakers, multimedia terminals, and smart audio systems.

Note: Adequate output power requires sufficient audio input level and adequate power supply voltage/current. Higher supply voltage produces higher output power. Speaker impedance also influences amplifier performance; under sufficient voltage and current conditions, higher impedance speakers produce lower output power.

100W ×2 High‑Power Stereo Audio Amplification

This Bluetooth stereo amplifier module delivers up to 100W per channel, providing strong output capability for passive speaker systems. Dual‑track left and right channels support clear stereo sound reproduction, making the board suitable for bookshelf speakers, portable audio builds, and compact home audio installations. Compatibility with 4Ω–8Ω passive speakers rated between 50W and 300W allows flexible integration across different DIY speaker configurations and enclosure designs.

Stable Output with Robust Power Design

The wireless audio amplifier board integrates four high‑quality 470µF capacitors to stabilize the power stage and maintain consistent audio performance under load. A dedicated heat sink combined with an efficient power management module supports long‑term operation during high‑output playback. This design improves electrical stability, minimizes distortion during peak output, and helps maintain reliable operation in continuous music playback or multimedia systems.

Integrated Protection and Enclosure Support

The stereo Bluetooth amplifier includes automatic overheat protection and short‑circuit protection to safeguard connected speakers and power systems. Protective top and bottom acrylic panels provide mechanical shielding for electronic components while maintaining ventilation for thermal dissipation. Such protection mechanisms make the audio amplification board suitable for embedded electronics builds, DIY speaker cabinets, and educational audio hardware prototypes.
