VHM-314 Bluetooth music module allows you to connect to a smartphone via a Bluetooth network. Thanks to the mini sound receiver, we can play music in WAV, APE, FLAC, MP3 format. Due to the low supply voltage of 3.7-5 V, it can be powered with a Li-Ion, 18650, Li-Pol 1S battery. The system is equipped with a blue LED indicating the operation of the device and a standard 3.5 mm Jack interface to which you can connect headphones, power amplifier and other devices.

MP3 player module that allows you to play files via Bluetooth 5.0. It is perfect for building a portable player for headphones or as a source for connecting to an amplifier. The signal-to-noise ratio (SNR) of 90dB and the harmonic distortion level of -70dB make the sound clear and enjoyable. The 3.5 mm JACK socket allows you to connect the AUX cable or headphones directly to the module. In addition, there is a place on the board for soldering wires at the output of the module. The 5V power source can be a USB charger from a phone, a USB port in a laptop or a power bank. The soldered micro USB socket allows you to easily connect the power source.
