PCM5122 HIFI Audio DAC Expansion Board For RPi


The HiFi DAC Hat is the best optimized partner for RPI audio output.
It is compatible with almost all raspberry pi with 40 pin gpio.
Used on-board PCM5122 as the I2S clock master, instead of the clocks from RPI which comes with too much jitter. Added dual low jitter oscillators(45.158M and 49.152M) to support more exact sample rate clocks. No soldering, no additional cables.
