BFKK X930 HiFi DAC HAT for Raspberry Pi

The BFKK X930 is a HiFi DAC HAT that adds high-quality audio to Raspberry Pi 4B, 3B+, 3B and 2B models. It uses the TI PCM5122 DAC to deliver 24-bit/192kHz playback with a 112dB SNR and 0.0019% THD. The board draws digital I2S signals directly from the GPIO header to reduce CPU load compared with USB audio devices.

Integrated CSR8675 Bluetooth 5.0 streaming

An on-board CSR8675 module brings Bluetooth 5.0 with aptX and aptX HD support, letting you stream 24-bit audio wirelessly from phones, tablets or laptops to the HAT’s RCA outputs. Hardware volume control via ALSA provides a full 2 V RMS signal, while the TI ultra-low-noise regulator keeps output noise below 10 µV RMS. On-board push buttons toggle Bluetooth or power the Pi without extra wiring.

Solder-free HAT installation and power management

The X930 stacks directly onto the Raspberry Pi GPIO header with no soldering or external cables required. Intelligent power management handles safe reboot, shutdown and full power-off from software to protect the OS image from corruption. Buyers who need built-in Wi-Fi streaming or a headphone amplifier on the same board will need a different solution.

Questions about this item

Will the TI PCM5122 DAC chip need any firmware updates or calibration over time?

The TI PCM5122 DAC operates without user firmware updates; its integrated hardware volume control and ultra-low-noise regulator are fixed-function circuits that do not require recalibration.

What limits continuous playback at 24-bit/192 kHz over Bluetooth 5.0?

The CSR8675 Bluetooth 5.0 module streams aptX HD at 24-bit quality, so the wireless link caps sustained throughput before the DAC’s 384 kHz capability is reached.

How much heat or noise does the HAT produce when stacked on a Raspberry Pi all day?

The board draws power through the Pi’s GPIO header with no active cooling; the TI voltage regulator’s sub-10 µVRMS output noise keeps thermal load negligible and audible noise absent.
