The MP3 Lossless Decoder Board with Power Amplifier Module offers seamless audio playback with versatile features. Equipped with a 2W mono amplifier (up to 3W with a 5V power supply), this module connects directly to 4Ω 3W speakers for clear sound output. It features a 3.5mm gold-plated headphone jack for external audio devices or headphones. The MicroUSB power supply interface supports mobile power banks, USB chargers, or a 3.7V lithium battery, offering flexibility in power options.



This decoder supports MP3 format, TF card, and U disk playback, with compatibility for a 16GB TF card and a 32GB U disk. The module auto-detects playback mode, defaulting to TF card mode but switching to U disk mode when the TF card is absent. The board also has easy-to-use speaker terminals that require no soldering, making wiring a breeze.
