The search term refers to an electronic component, most likely a Hall Effect Sensor or a Magnetic Latch/Switch . The prefix "VHM" is commonly associated with the manufacturer Honeywell (or subsidiary brands acquired by Honeywell) or specialized automotive/industrial sensor lines.
If you are planning a project with this module, tell me you are building (e.g., car stereo, boombox, headphone amp) and what power source you plan to use. I can provide a custom wiring layout or component recommendations! Share public link
: It can be powered via a Universal Micro USB/Type-C 5V port or through dedicated 3.7V lithium battery pads (VBAT/GND).
Sharing a single power supply between the VHM-314 and an audio amplifier board often creates an electrical ground loop, introducing high-pitched digital noise or buzzing into the audio stream. vhm 314 datasheet free
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
: Use the Micro-USB Port for 5V power or the BAT+ and BAT- pads for a lithium battery.
According to technical documentation, the VHM-314 has the following specifications: Specification Operating Voltage (Micro USB or Battery) Signal-to-Noise Ratio (SNR) ≥90dBis greater than or equal to 90 d cap B THD+N -70dBnegative 70 d cap B Crosstalk -86dBnegative 86 d cap B DNR 91dB91 d cap B Support Profiles A2DP/AVCTP/AVDTP/HFP Transmission Distance (open space) Output Interface Stereo Jack Dimensions How to Find the VHM-314 Datasheet Free The search term refers to an electronic component,
Identify the original manufacturer by looking at the logo on the component. Common manufacturers for the 314 series include , Honeywell , or Texas Instruments . Go to their "Product" or "Parametric Search" section, type "VHM 314," and look for the "Technical Documents" tab.
Can be powered via a standard Micro-USB cable or a direct DC power supply.
Contains only the basic receiver circuitry, power ports, and audio outputs as described above. I can provide a custom wiring layout or
The VHM-314 board is compact (approx. 30mm x 30mm) and designed for easy installation. It features two primary connection zones. Power Inputs
Don’t let a bad number ruin your project. Decode the marking, find the real part, and get back to building.
Accept standard 5V DC power from phone chargers or power banks.
