Audio Voice Module Board

The Vszerda Audio Voice Module Board is a compact sound card that decodes MP3 audio from TF cards or USB flash drives. It is designed for hobbyists and developers who need a simple playback module for voice prompts, alerts or background music in embedded projects. No host computer is required once media is inserted.

Thermals noise and power draw

The board draws minimal current during playback and runs without a fan or heatsink. In normal use it remains cool to the touch and produces no audible noise of its own. Power is supplied through the onboard USB or pin header, so total system draw depends only on the chosen source.

Domande su questo articolo

How do I wire the Vszerda Audio Voice Module Board to my circuit?

Connect power to the VCC and GND pins, then attach a speaker to the SPK+/SPK- terminals; the common mistake is reversing the speaker polarity which mutes the output.

What upkeep does the TF-card slot and USB port on the Vszerda board require?

Keep the TF-card contacts clean with a dry brush and avoid bending the USB connector; the onboard flash memory has no moving parts and needs no scheduled replacement.
