To get the best performance from your VHM-314, keep these points in mind:

Audio is actively streaming or playing through the module. Bluetooth Pairing Process Supply power to the board via USB or the BAT pads.

Use the datasheet for the Allegro A3144 or Honeywell SS400 series as a reference for pinout and voltage parameters. These are free, widely available, and electrically compatible.

For advanced DIY integration, the board includes several solder pads alongside the standard connectors: : Primary 5V power input.
