Upgrade any compact space or DIY audio build with the Mini 2x3W Stereo Audio Amplifier Board with Bluetooth 5.0, a complete plug-and-play power stage that eliminates messy wiring and outdated sound processing. Engineered with a highly efficient Class D topology, this kit delivers 2 × 3W RMS across both channels while drawing only 0.5A to 2A, keeping heat output low and extending runtime when powered by DC 3.7V–5V sources such as USB chargers or lithium power banks. The machined aluminum alloy casing protects sensitive routing, improves structural stability, and acts as a passive heatsink for sustained performance. Native 5.0 Bluetooth provides stable wireless streaming up to 10 meters, while onboard digital decoders handle MP3, WMA, WAV, and FLAC files directly from attached USB flashes or TF/Micro SD cards. Legacy gear connects instantly via the standard 3.5mm AUX jack or by scanning accessible FM bands, giving you four distinct input pathways in a single compact footprint.

Benefits & Practical Usage Tips

  • True Battery Operation: Route power from a standard 5V mobile power bank into the input screws for completely untethered listening during travel, picnics, or field recordings.
  • Vintage Restoration: Strip faded factory amplifiers from old boomboxes or wall-mounted speakers and replace them with these screw-terminal inputs for instant modernized clarity.
  • Format Selection Strategy: Reserve the TF card slot for high-bitrate FLAC music when critical detail matters most, and lean on Bluetooth 5.0 for everyday podcast or streaming convenience.
