It supports lossless audio decoding for multiple popular music formats to deliver high-quality stereo sound with minimal latency and distortion.

A standout feature of this module is its dual-power flexibility. It can be conveniently powered via its onboard Micro-USB port (5V) or by soldering a standard 3.7V to 5V lithium battery directly onto the dedicated power pads. For audio routing, it includes a convenient onboard 3.5mm audio jack for plugging in headphones or AUX lines, alongside direct solder pads (Left, Right, Ground) to easily wire the audio feed into an internal amplifier board.
