Boards you can build
Below are links to overview pages for board designs currently available. Each page gives a small summary and overview of the board, along with power supply and suggestions for other hardware requirements. Each page has a link to the GitHub repository for the board.
Control & DSP Boards
CoreOne
An XMOS 200 based control and DSP PCB design with USB, SPDIF, I2S/TDM, SPI, I2C, and Ethernet connectivity options. Design files on GitHub.
uDSP
A miniaturised version (5cm x 5cm) of the existing DSP board. All I/O routed.
Design files on GitHub.
An Analog Devices SigmaDSP ADAU1450/1451/1452 board.
This DSP board features 4 I2S inputs, 4 I2S outputs (all chips), SPDIF inputs and outputs (optical and coax, on the 1451 and 1452 chips). This is a fully self-booting (once programmed) DSP board.

DAC Boards and Buffers
uCODEC
A miniature CODEC board (5cm x 5cm) with 4 analogue differential inputs and 8 analogue differential outputs.

ADAU1966 with Passive Filters (16 Differential Outputs)
This board features the ADAU1966 16 channel DAC chip. This uses 4xTDM4 or 2xTDM8 or 1xTDM16 digital inputs (I2S connector) to give 16 differential audio outputs. This has only passive filters on the DAC output but is capable of driving external PCBs without issue.
Differential to Single Ended Active Buffer
A differential to single ended active buffer for use with the ADAU1966 DAC board. With 8 differential inputs and 8 single ended outputs.
