DFRobot DAC Audio Decoder Board for Raspberry Pi 3B+/ 4B
DFRobot DAC Audio Decoder Board for Raspberry Pi 3B+/ 4B supports decoding of I2S and DSD digital audio signals output from the Raspberry Pi motherboard. This board also supports I2S/DSD/coaxial input, analog/coaxial/optical/I2S output, 384K/32Bit decoding function, and unique DSD clock de-jitter. The DAC audio decoder board can also decode external coaxial signals by setting the three buttons on the board. This decoder board is capable of independently turning ON or OFF the audio output signal of each interface through the button on the board. The DAC audio decoder board uses four professional chips and two groups of LDO to power analog and digital circuits separately. Solid capacitors with large capacity and tantalum capacitors are used for filtering and decoupling to ensure a stable and clean power supply and effectively improve the overall Signal to Noise Ratio (SNR).Features
