The blue LED indicator will flash rapidly, indicating it is in pairing mode.
Sometimes, "VHM 314" is a proprietary or OEM number. If you search for a and come up empty, do this:
Retailers often provide specifications in their product descriptions, which can serve as a functional datasheet in a pinch. For example, the listing from Kamami.pl provides an excellent summary of features, while the technical details on Roboshop.spb.ru offer practical usage notes. The following table summarizes useful sources discovered during research: vhm 314 datasheet free
A blue LED flashes when in Bluetooth pairing mode and stays solid blue once a connection is established. How to Use the VHM-314 Board
However, I can provide you with some general information about the module and its features, which might be helpful: The blue LED indicator will flash rapidly, indicating
Turn on Bluetooth on your source device (Phone, Tablet, PC). Search for nearby devices and select .
Most VHM 314 variants operate between . The datasheet will specify if it is a 5V-only device or if it supports 12V industrial rails. Look for the "Supply Voltage Rejection Ratio" – how well the device ignores noise on the power line. For example, the listing from Kamami
relies on the . It delivers high-fidelity sound across standard wireless configurations.
