more info here"This is a small project focused on audio signal processing using the Microchip dsPIC. It provides the following features:
* Microchip dsPIC33FJ32GP302 Microcontroller with 32kB Flash, 4kB SRAM, ADC, Codec interface, I2C, SPI, etc.
o Pin-compatible with other dsPIC parts for expanded Flash, SRAM, peripherals.
* Wolfson WM8731 stereo audio CODEC with up to 96kHz / 24-bit sampling.
* Microchip 23k256 SPI 32kB SRAM.
* Microchip 24aa256 I2C 32kB EEPROM.
* Off board stereo audio I/O (+/-5Vpp, AC-coupled)
* Off board analog CV / Pot port with 4 x 10V CV + offset pot.
* Off board analog/digital expansion port with 8 MCU I/O.
o Up to 2x 12-bit ADC inputs.
o Up to 8x GPIO with pulldowns for switches / encoders
* Codec expansion port with headphone driver output and microphone input
* ISP port for MCU development and debugging
The principle reason for this board is development and deployment of simple audio DSP applications."
