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 | 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 [[NASPiDACPi]], and we only use [[P165 | P165-B]] to dissipate heat, which can provide enough heat dissipation if there is no overclocking, but [[P165 | P165-B]] may be a slight impact on WIFI. You can remove the heatsink also.
