WWZMDiB MP3 Decoder Module 2-Pack - Lossless Audio Player With TF Card & USB Support

About This Product

So if you're into DIY audio projects or need a simple MP3 player solution, these little decoder modules are pretty awesome. Each one is about the size of a matchbox (45x36mm to be exact) but packs some serious functionality. They support MP3 format and can play directly from TF cards (tested up to 16GB) or USB drives (up to 32GB). The cool part is they automatically detect what's connected - if there's no TF card, it switches to USB mode. Sound quality is actually really clean with this onboard 2W mono amplifier that can push up to 3W with 5V power. You can hook them up directly to 4Ω speakers without needing extra amplification. Powering them is super easy too - they work with anything from 3.7V to 5.5V, so you can use a mobile power bank, USB charger, or pretty much any DC power source through that Micro USB port. The controls are simple but effective - short presses for track skipping and play/pause, long presses for volume control. There's even a red LED that shows playback status. I've used these for several projects including a custom boombox, a background music system for my workshop, and even a talking Halloween decoration. The fact that you get two modules in the package means you can set up multiple systems or have a backup. They come with a 30cm USB cable too, which is handy. For Arduino tinkerers, these work great with the SD card library. If you need an affordable, compact MP3 solution that just works without complicated setup, these modules deliver exactly what you need.
