I started my DAC project for the Raspberry Pi. The first version runs as an I2S slave device and already works very well. On-chip PLL automatically syncs to different clock frequencies. Analog power is supplied by an additional low-noise voltage regulator.
![]() HiFiBerry Mini | Crazy Audio I will do more measurements next week. Version 2 is in design phase. It will be a bit more complex: - onboard oscillator, runs as I2S master - DAC chip with I2C control (volume control, sample rate, minimal DSP postprocessing) Regards Daniel |

Nice one!
I am curious how far this will develop. Which DAC did you use? |

The DAC chip is a PCM5102. Version 2 will use a PCM5122 which will act as master for all clocks.

Hi,
Are these for sale as kits or assembled?

Not yet, but in about 2 months. I will also test another DAC/voltage regulator combination and see, what sounds best. Most likely there will be a kit with all SMD components soldered. Some soldering is needed, because the P5 header has to be soldered on the Raspberry.

Nice, very interested in this project, any evaluation boards available prior to launch?
As an aside could you supply the board without phono sockets? |

@smallangryboy: There are 2 eval boards of the prototype, these are already reserved for 2 guys. There might be another 2 eval boards of version 2. The phono sockets will be parts of the kist, however, you do not have to solder them on the board.
@Turbon: This is not a USB DAC, it connects directly to the I2S port of the SoC. Last edited by usul27; 21st October 2013 at 01:12 PM. |
