Oaqmvgin Bluetooth Amplifier Board 2.1 Channel 3-Pack TPA3116D2 ready Kit Three pack module bundle for flexible multi-speaker projects; includes amp boards quick builds.

Protection mechanism: overvoltage, undervoltage, overheating, DC detection, short circuit protection Wide range of uses: suitable for high quality and professional audio equipment, instruments, control circuits and telephone channel amplifiers. Stable performance: with better noise performance, excellent output drive capability and relatively high small signal bandwidth, large power supply voltage range. : When the audio input is enough and the power supply voltage/current is enough, there be enough output power The higher the power supply voltage, the greater the output power, the smaller the speaker impedance, the greater the output power Please make sure that the power of the adapter power is the actual working power of the amplifier It has the characteristics of small size, high efficiency, high power and small heat.
