Overview

Geekworm DACPi is an ultra-thin desktop DAC kit based on the latest raspberry pi 4;

We know that there are many DAC expansion boards released on the market, but they have a common shortcoming that they are too thick. We redesigned the DAC expansion board (X950) and tried our best to make this DAC the thinnest and matched a NUC style aluminum alloy shell, the final thickness of DACPi is only 31mm, Geekworm hope you can like it.

DACPi adopts modular design, it composed of three parts: X950 DAC Shield, cooling system ( P165-B embedded heatsink), and a ultra-thin NUC style aluminum case;Just simply assemble them with the Raspberry Pi 4 motherboard.

  • X950 shield can turn your Raspberry pi 4 into a ready-to-play High Resolution Network Music Player.
  • The shell is made of all aluminum alloy, CNC processing method, surface anodizing treatment.
  • For the cooling solution, considering that the active cooling fan will interfere with the sound quality, we abandoned the X823-A3 active cooling solution in NASPi, and we only use P165-B to dissipate heat, which can provide enough heat dissipation if there is no overclocking, but P165-B may be a slight impact on WIFI. You can remove the heatsink also.

Hi, for me it works only with dtoverlay=hifiberry-dac on the config.txt file.

aplay -l comand gave me that it is a PCM5102a and not a PCM5122

pi@moode:~ $ aplay -l

The same with RaspianOS, Volumio3, and rAudio1.

With the latest Rasbian, this does not work. I have tried both overlay lines. The original one does show errors inn syslog when audio is played. The second one does not, but, still no audio is output.

With max2play the 1st time it comes up will show big blocks can pick for the audio DAC. Just pick "IQaudIO Pi-DAC+" Must be the same audio chip this uses and reboot and play your music. Works real good.
