The VHM-314 is a compact, low-cost Bluetooth audio receiver module. Its primary function is to receive a wireless audio stream from a source like a smartphone, tablet, or computer and output it as a standard analog stereo signal, typically through a 3.5mm headphone jack. In essence, it can turn any wired speaker, old car stereo, or DIY audio project into a Bluetooth-enabled device.
The VHM-314 board is compact (approx. 30mm x 30mm) and designed for easy installation. It features two primary connection zones. Power Inputs
of continuous current. If using a lithium battery, recharge it to bring the voltage back above the minimum operational threshold. Issue 3: Limited Bluetooth Range
