DAC Audio Decoder Board for Raspberry Pi 3B+/ 4B

This Raspberry Pi DAC Audio Decoder Board elevates digital sound experiences with its innovative capabilities. It proficiently supports I2S, DSD, and coaxial inputs while offering multiple outputs such as analog, coaxial, optical, and I2S. Its impeccable 384K/32Bit decoding capacity is enhanced by a unique DSD clock de-jitter mechanism, ensuring pure audio fidelity.

Seamlessly integrating with a Raspberry Pi motherboard, this board decodes I2S and DSD signals effortlessly. Users can easily manage their listening experience by using three buttons on the board to switch between input formats like the I2S and external coaxial signals. All outputs can be individually activated or deactivated, optimizing user-specific audio preferences.

Equipped with four high-performance chips, this audio decoder ensures unmatched performance. Two groups of LDO (Low Dropout Regulators) separately power analog and digital circuits, resulting in a superior signal to noise ratio (SNR). With solid capacitors and tantalum capacitors, the board maintains a stable and clean power supply, significantly enhancing sound clarity.

Technologically advanced features like the TI PCM9211 chip, with a 216KHz sampling rate and ultra-low jitter, set this board apart. The TI PCM5122 DAC chip provides high SNR of 112dB for richer sound details and dynamics. High-speed LVDS output ensures distortion-free transmission, while SiTime crystal oscillators offer ultra-low jitter for pristine sound reproduction.

An onboard OLED display adds further convenience, showing the current track sampling rate and signal format at a glance. Advanced settings are accessible via an intuitive interface, allowing users to customize parameters with ease by using onboard keys. This meticulous attention to detail transforms every sound experience into a nuanced auditory journey.
