The VS1053 Simple DSP Board is a small, low-cost and high performance audio DSP board for the VS1053 audio codec IC from VLSI Solution. It is meant to be used in DSP software development and as a plug-in module in electronic applications.
The VS1053 Simple DSP Board has two rows of pin headers, one on each edge of the board. One edge has digital connections for connecting to a serial port or to an SPI port. This can be used to interface the board with a PC and VSIDE or a host microcontroller. The other edge has analog connections featuring Line In, Line Out and Headphone Out. Line In and Line Out are AC-coupled and can be connected directly to other audio circuits.
The board has necessary power supplies, four LEDs and a button for the user interface. A boot EEPROM is included so that application software and also sound samples can be stored on the board.
The VS1053 Simple DSP Starter Kit and the VS1053 Simple DSP Professional Kit include everything needed to start developing applications for the VS1053.
