How to assemble it?

  • Please assemble the hat board according to following figure:

Package Includes


  • 1 x 52Pi NVDAC board
  • 1 x PC104 pin header
  • 1 x M.2 2230 fixing copper pillar
  • 2 x Black M2.0 fixing screw for SSD drive
  • 1 x PCIe FFC cable (40mm length)
  • 4 x M2.5 Copper pillar
  • 4 x M2.5 Screw
  • 4 x M2.5 nuts

How to enable DAC

  • HiFi DAC has two line out connector. A double phono/RCA connector, normally red and white in colour, and a 3.5mm Line out Socket.

This output is a variable analogue signal (0-2V RMS) and can connect to your existing hi-fi (pre-amp or amplifier), or can be used to drive active speakers which have their own amplifier built in.

  • White:LEFT audio
  • Red:RIGHT audio

How to enable DAC on Raspberry Pi 5?

  • On Raspberry Pi 4B

Adding following part in /boot/config.txt file or /boot/firmware/config.txt file in latest OS and reboot Raspberry Pi.

  • On Raspberry Pi 5

Modify /boot/config.txt file or /boot/firmware/config.txt file in latest OS. If you need to support Raspberry Pi 5, you need to add the additional dtoverlay parameter as follows:


and save it, reboot Raspberry Pi 5.
