Overview
The X930 HiFi DAC for Raspberry Pi adds a high-quality sound to your Raspberry Pi. It is designed for
optimal sound output quality and the ideal HiFi solution for all Raspberry Pi users that love music.
It supports intelligent power management, safe reboot, safe shutdown and full poweroff from software.
The most efficient way to avoid OS image corruptions & other issues that can damage your Pi! The
on-board push buttons can be used to switch on or off Bluetooth or Raspberry Pi.
Easy to use & installation - The X930 connects directly to the Raspberry Pi where no external cables are
needed. No need to solder any header or wire, just stack it on top of your Raspberry Pi because it
corresponds to the Raspberry Pi Foundation's HAT size including mounting holes and form factor.
