    Well worth the money

    Posted by Digilent Customer on 9th Aug 2020

    Recently I have been doing some experiments with digital filters, and originally I was considering making a PCB myself to do all the filtering for frequencies about 24 kHz, but this offered a much faster way to get up and going. Within an hour I was able to get it working, and I also appreciate the inclusion of the schematic so I can include this in future designs.

    High quality module and best converters resolution in the market. Thanks to Pmod connector, It has short time to use and implement in a new designs.

    Finally a stereo audio PMOD!

    I got this working with my Arty in less than an hour, using the demo designs provided. There's never been an easier to use high-quality stereo audio interface. No SPI registers to set up, just give it the right clocks and the audio data flows through. Nicely done Digilent!
