Mini MP3 Player Module for Arduino

This module reads TF cards up to 32 GB and exposes a USB port so the card appears as a removable drive on a computer. It accepts a 5 V supply and drives a speaker through an 8002 BTL amplifier rated at 3 W. Control is handled by a 9600 baud serial link or the onboard buttons, making it suitable for embedded audio projects.

Check power and card limits before ordering

The board requires a stable 5 V source; verify your host can deliver enough current for the 3 W amplifier. Only TF cards of 32 GB or less are supported, so larger cards will not be recognised. The USB interface is for card-reader access and audio playback from the host, not for firmware updates or advanced configuration.

Sustained playback stays within the 3 W envelope

During continuous operation the 8002 BTL amplifier delivers its rated 3 W output without thermal throttling, provided the 5 V rail remains steady. The 9600 baud serial link and button inputs remain responsive over long sessions, and the USB card-reader function does not degrade when the module is powered for extended periods.

Questions about this item

Does the module come with a TF card or USB cable, or must they be purchased separately?

The package includes only the Mini MP3 Player Module board; a micro-SD card up to 32 GB and a USB cable for power or data are not supplied.

Which storage capacity should I choose for the TF card slot?

The board accepts micro-SD cards up to 32 GB, so any card at or below that limit will work.

What does the 3 W output with the 8002 BTL amplifier mean for actual playback volume?

The on-board 8002 BTL amplifier can drive a small speaker at up to 3 watts, suitable for voice prompts or moderate-level audio in a quiet environment.
