This is a low-power audio receiver board which supports Bluetooth 4.2, with two-channel stereo lossless playback. It can drive speakers (2-8 ohm, 3-5W).
This Bluetooth audio module is based on the MH-M38 IC, and 5V amplifier ICs, one for each channel.
Power supply: You can directly use a micro USB cable or connect a 5V power supply or 3.7V lithium battery. Note that to connect the 3.7V lithium battery, this must be connected to VBAT and GND
The maximum operating current is 5V2A, and it is recommended to use a regulated 5V2A power supply for better sound quality.
Supports USB sound card, plug-and-play. You can also connect the module to the computer with a USB cable, and it will play music through the module’s amplifier output.
Audio output: Outputs left and right stereo audio signals, which can be connected to two 2-8ohm, 3-5W speakers, and 4 ohms 5W speakers.
5W power amplifier on board: It has its own dual 5W amplifier circuit, and must not be connected to another amplifier. The outputs of the two amplifiers may not be connected in parallel or the negative poles may be connected together. Otherwise, the power amplifier chip may be damaged.
