BEpp is an audio DSP board for musical instruments. Features:

• 24 bit AK4556 codec
• Mono input sampled with two different gain stages - inspired by Line6 POD XT Live
• Two output channels and headphone driver with independent volume controls
• Cortex-M7 core with 2 MB program flash and 384 kB RAM, optionally configured for 128 + 128 kB TCM use
• 8 MB external SDRAM and Winbond W25Q series serial flash
• A lot of configurable IO - LCD interface with SPI, UART for MIDI, analog inputs, PWM out, GPIO etc.
• USB
• 9V AC supply
• All on a two layer board - I know the risks but I'll give a try
