💻 Product Overview
The VS1003B is a single-chip audio decoder and encoder module built around the VS_DSP4 processor core. It decodes MP3, WMA, WAV and MIDI streams and can encode IMA ADPCM from a microphone or line input, which makes it useful for embedded audio projects, custom players and co-processor designs. On-chip stereo DAC, earphone driver and serial interfaces keep the audio path compact.
