Description
This Mini Bluetooth audio digital USB power amplifier board is a 2 channel 3W, Class D amplifier board. This is defined as a perfect device for converting a regular speaker to a Bluetooth speaker. This amplifier board supports Bluetooth audio input and DC 5V voltage input by micro USB. This module is capable of turning normal speakers to Bluetooth applicable speaker impedance of  4/6/8ohm.
The heart of this Mini Bluetooth audio digital USB power amplifier board is a PAM8403 audio amplifier chip. It allows the device to drive the speaker directly, requiring no low pass output filters. As a result, save the system cost and PCB area. This module operates at a voltage of  DC 5V.or by USB supply directly. This audio amplifier offers high efficiency and high-quality sound reproduction makes it ideal for DIY Bluetooth speaker, home, and car audio system modification. With the same no of external components, this digital amplifier board performs much better than class-AB amplifiers. This dual-channel stereo output power can directly drive the 4 Ohm /6 ohm/8 Ohm small speakers.
This Mini Bluetooth audio digital USB power amplifier board provides a high amplification 3W of power at efficiencies greater than 90% with both system shutdown and mute control. This module features low Quiescent Current, low EMI with short circuit, and thermal shutdown protection. And also used for a long time steady usage as it features low harmonic distortion. Moreover, this 3W dual audio amplifier designed with special inline architecture enhances anti-noise capability and reduces RF interference.
