The upgraded DAC chip adopts the higher-end PCM5122 chip of BB Company, adopts 25 interface and can adjust the volume and audio parameters through the 12C interface; supports 16 to 32-bit audio data format; distortion and dynamics are very ideas, support high 384kHz sampling rate, dynamic range 112dB, distortion -93Db. 120dB squelch signal-to-noise ratio (SNR) for soft up or down ramps and analog squelch with no pops operation.pcM5122 also integrates a negative charge pump, and the output does not need a DC blocking capacitor; 2.1vrms grounded center output; very good ability to suppress out-of-band noise. By supporting loads as low as 1k ohm, the PCM510XA can drive multiple products in parallel.The output port adopts gold-plated RCV dual terminals and gold-plated 35mm headphone jackThe isolated power supply design is adopted to isolate the Raspberry Pi power supply from the DAC part of the independent power supply, and the common ground of the magnetic beads does not interfere with each other, so as to get rid of the current noise.No soldering, it can be used directly by plugging in the expansion board, and the I25 interface is used to directly decode the digital to analog non-USB interface DAC methodAdded to provide status display for two-color Led, the red light is the DAC power indicator (the power is on normally), and the green light is the DAC working status light (on when working and decoding, off when stopped or not working), to better understand the working condition of the DACThe pcB board adopts high-grade gold-plated process and arc-shaped wiring to better ensure the impedance continuity of the signal and reduce the reflection and refraction of the signal.colour: blueMaterial: PCBPackage Contents:1 x Expansion Board1 x Screw PackOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
