VS1011 MP3 Decoder Module

VS1011 Module is a module for developing MP3/WAV player application with existing microcontroller board. The module comes with IC MPEG decoder VS1011e. It requires 7 pins for SPI signals, reset and data request signals. The module supplies one audio jack connector for earphone or speaker for audio output only and doesn’t support sound recording.

Note that the host board to be connected with VS1011 module should have its own memory storing audio file.

Features:

• Decodes MPEG 1.0 & 2.0 audio layer III (CBR, VBR, ABR); layers I & II optional; WAV (PCM + IMA ADPCM)
• 320 kbit/s MP3 with 12.0 MHz external clock
• Streaming support for MP1/2/3 and WAV
• Bass and treble controls
• Operates with single 12..13 MHz or 24..26 MHz external clock
• Internal clock doubler
• Low-power operation
• High-quality stereo DAC with no phase error between channels
• Stereo earphone driver capable of driving a 30­ ohm load
• Separate 2.5 .. 3.6 V operating voltages for analog and digital
• Serial control and data interfaces
• Can be used as a slave co-processor
• 5.5 KiB On-chip RAM for user code / data
• SPI flash boot for special applications
• New functions may be added with software and 4 GPIO pins

Items included:

• VS1011 module
• Headphone
