VHM-314 Bluetooth Audio Receiver Module: Pinout, Specs, and Full Datasheet Guide
The VHM-314 is a highly popular, low-cost Bluetooth 5.0 audio receiver module frequently used by DIY enthusiasts to add wireless connectivity to speakers, car stereos, and headphones. Despite its small footprint, it offers impressive audio clarity and ease of use.
Below is a comprehensive technical guide and datasheet overview for the VHM-314. Understanding the VHM-314 Hardware
The VHM-314 is designed for simplicity. It typically features a micro-USB port for power and a 3.5mm jack for audio output, making it a "plug-and-play" solution for most applications. Technical Specifications
Bluetooth Version: 5.0 (Compatible with 4.1, 4.2)Power Supply: 3.7V to 5V DCCurrent Consumption: 20mA (Operating), 10mA (Idle)Signal-to-Noise Ratio (SNR): 90dBTotal Harmonic Distortion + Noise (THD+N): -70dBCrosstalk: -86dBDynamic Range: 91dBSupported Decoding: WAV, APE, FLAC, MP3Transmission Distance: Up to 15 meters (line of sight) Pinout and Connection Ports
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 If you have more details about the supplier
Powering the Module: Supply 5V via the Micro-USB port or solder a 3.7V battery to the BAT terminals. Note: Do not supply 5V to the battery pads as it lacks a charging circuit.
Pairing: Once powered, the blue LED will flash rapidly. Search for "VHM-314" on your smartphone or PC Bluetooth settings and select "Connect."
Audio Output: Plug your speakers or headphones into the 3.5mm jack. If using an external amplifier, use the L/G/R soldering pads for a cleaner signal path. Key Features and Benefits
Lossless Decoding: Supports high-fidelity formats like FLAC and APE, ensuring high-quality audio streaming.Compact Form Factor: Measuring roughly 30mm x 30mm, it fits into almost any enclosure.Auto-Reconnect: Automatically pairs with the last known device upon power-up.Low Latency: Bluetooth 5.0 technology reduces audio lag compared to older 4.0 modules. Safety and Installation Tips
Power Isolation: If you experience "ground loop noise" (humming) when using the module in a car, use an isolated DC-DC power converter.Antenna Clearance: Avoid placing the module behind thick metal plates, as this will significantly reduce the Bluetooth range.No Charging Circuit: If using a battery, you must use an external TP4056 or similar charging module to recharge the battery safely.
The VHM-314 remains the gold standard for budget Bluetooth upgrades due to its reliability and straightforward design. Whether you are reviving an old hi-fi system or building a portable boombox, this module provides a professional-grade wireless link at a fraction of the cost of commercial receivers.
