Bluetooth Audio Module VHM-314 MP3 Decoder Lossless & Wireless Stereo Music Amplifier Board XY-BT-Mini Review

Bluetooth audio module VHM-314 is designed to transmit a stereo audio signal via Bluetooth. The basis of the module is the AC1847AP1P803 chip. The module can be powered both from a 5V DC source and from a Li-Ion battery with a voltage of 3.7 to 5V. The sound output is a 3.5 mm Jack connector, in addition, there are three pads on the board, marked as “L”, “G” and “R”, to which you can solder wires to remove the output signal. In fact, they are connected in parallel with the connector. Bluetooth V5.0 version function, support Bluetooth auto connection technology, support WAV / WMA / FLAC / APE / MP3 lossless decoding, stereo two-channel output. When the module is turned on, the red LED in the search mode starts blinking twice per second. If the connection is successful, the blink rate drops to once every five seconds. Connecting and disconnecting the module is accompanied by sound signals notifying the user about the change in the operating mode.
