Raspberry Pi DAC Pro

The Raspberry Pi DAC Pro is Raspberry Pi's highest-fidelity audio HAT, compatible with any Raspberry Pi computer that has a 40-pin GPIO header.

It supports the same audio input formats and output connectors as the Raspberry Pi DAC+, but uses a Texas Instruments PCM5242 DAC, providing an even higher signal-to-noise ratio.

With the Texas Instruments PCM5242, the DAC Pro provides an outstanding signal-to-noise ratio (SNR) and supports balanced/differential output in parallel to phono/RCA line-level output. It also includes a dedicated headphone amplifier.

As part of the DAC Pro, two three-pin headers (P7/P9) are exposed above the Raspberry Pi’s USB and Ethernet ports for use by the optional XLR board (coming soon), allowing differential/balanced output.

The DAC Pro does not require external power and connects directly to Raspberry Pi’s GPIO header without the need for soldering or cables.
