Open the Bluetooth settings on your smartphone, tablet, or computer. Scan for new devices and select from the list.

Micro-USB Port: Power the module using any standard 5V USB charger or power bank.BAT Pads (+ and -): Connect a 3.7V Lithium-ion battery for portable use.3.5mm Stereo Jack: Connect directly to headphones or an amplifier input.Audio Output Pads (L, G, R): Direct soldering points for Left channel, Ground, and Right channel for permanent installations.LED Indicator: Blue light flashes during pairing and stays solid when connected. How to Use the VHM-314

The VHM 314 is a type of electronic component, likely a voltage regulator or a power management IC. Without a datasheet, it's challenging to determine its exact specifications and applications. However, with the datasheet, you'll have access to crucial information such as:

Connect 5V to the USB port or 3.7V to the battery pads. The blue LED will start flashing. vhm 314 datasheet free

Audio Ground (Keep separate from power ground where possible to avoid ground loops). Status Indicator (LED)

Voltage drops caused by low battery capacity or a weak USB power brick.

If the part is truly custom (e.g., a coded IC from a specific laptop motherboard or car ECU), the public datasheet may not exist. Here is your workaround: Open the Bluetooth settings on your smartphone, tablet,

Ground connection for the external power supply. Audio Output Interfaces

Use an isolated DC-DC converter module (such as the B0505S-1W) between your main power source and the VHM-314. Alternatively, power the Bluetooth receiver using a completely independent power source. Issue 2: Audio Distortion or Intermittent Cutouts Cause: The input voltage dropped below the required

The VHM-314 is a highly popular, low-cost Bluetooth audio receiver board used extensively by DIY electronics enthusiasts. It allows you to add wireless Bluetooth audio connectivity to old amplifiers, wired headphones, car stereos, and custom speaker builds. How to Use the VHM-314 The VHM 314
