Descriptions

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 features CSR8675 flagship Bluetooth 5.0 module to ensure high quality remote audio streaming. It brings new life to traditional electronics like home speakers, wired headphones to receive wireless music from cellphones, tablets, laptops, etc. It supports aptX, aptX HD and Active Noise Cancellation. Standard CD quality is 16bit. Using aptx-HD wirelessly stream 24bit music quality for a "better-than-CD" listening experience. 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. The BT module is not included, we still haven't produced it.
