Because multiple manufacturers produce legacy components with similar naming conventions, the official datasheet is the only truth source. Searching for a free PDF ensures you don’t pay for a document that should be publicly available from distributors.
For advanced DIY integration, the board includes several solder pads alongside the standard connectors: : Primary 5V power input.
Open Bluetooth settings on your phone/laptop and search for devices. Select the device named "VHM-314" or similar (sometimes "XY-BT").
Hall sensors can be slow. The VHM 314 datasheet will list the (typically 20kHz to 100kHz). If you are sensing high-frequency currents (e.g., switching power supplies at 500kHz), you need a high-bandwidth variant. vhm 314 datasheet free
The VHM-314 is user-friendly, designed for simple integration. Power Input You can power the board using: Standard Pad: For soldering a Lithium battery directly to the board. Audio Output Jack: Connects directly to speakers or an amplifier.
First, let’s address the elephant in the room. There is no standard industry-wide component labeled "VHM 314."

Can be powered via Micro USB (5V) or an external 3.7V - 5V lithium battery.
Websites like alldatasheet.com or datasheetarchive.com index millions of components. Type VHM 314 into their search engine. Look for results with “Vacuumschmelze” as the company. Click “Free Download”. These sites run on ads, but the PDF itself is free.
is a popular, low-cost Bluetooth 5.0 audio receiver module frequently used in DIY audio projects. While a formal multi-page "datasheet" from a single manufacturer can be hard to find, the technical specifications and interface details are well-documented across several supplier resources. 📋 Key Technical Specifications Bluetooth Version: 5.0 (backward compatible with 4.0, 4.1, and 4.2) Operating Voltage: 3.7V to 5V DC Power Options: The VHM 314 datasheet will list the (typically
External power supply terminals. The positive pad is used for connecting lithium batteries (
