PCB for the ADAU1701 Universal Audio DSP Board as published in Elektor Magazine January/February 2014 double edition.
'Drag `n drop DSP-ing'. This Universal Audio DSP board for the DIYer is based on the Analog Devices ADAU1701 DSP and has only through-hole components -- except for the DSP itself. Together with the associated (free!) development environment called SigmaStudio the chip is targeted at those who want an easy migration path from all-analog audio signal processing designs and moving into the digital domain. SigmaStudio requires no programming -- just drag and drop prebuilt blocks such as 'State Variable Filter' and you have a circuit ready in just minutes which can either be implemented as a DSP platform or simulated using this board and then implemented as an analog platform!
