PiFi Digi+ Pi HAT For Raspberry PI

PiFi Digi + Pi HAT For Raspberry PI

feature:
1. High-end digital chip WM8804G chip, I2S interface; supports 16-24 audio data formats; distortion and dynamic very good, up to 192kHz sampling rate support, advanced damping technology inherent jitter (inherent periodic jitter) control Within 50ps RMS, highly reduced.
2. Using optical fiber and coaxial output two output interface, user-friendly external amplifier
3. Support hardware volume control (I2C interface)
4. Power supply using raspberry pie, no external power supply; and π-type filter power supply design, effectively reducing the power supply interference
5. I2S interface with direct digital output, reproducing high non-USB interface DAC mode, do not use other extensions Raspberry Pi GPIO
6. Provide power indicator light, easy to observe the expansion board status
7. Placing a PCB on a highly bent trace (high-end HIFI DACs with arcuate traces) to better guarantee the continuity of the impedance signal and reduce signal reflections and refractions.
8.Good sound Thanks to the real material, the optical interface adopts the imported HIFI grade high-quality fiber base, the coaxial interface adopts the Pluse imported audio isolation transformer, meanwhile provides the good audio digital audio equipment! ! (The cost of similar products abroad has been removed, in order to sound good, reliability, we will not begrudge the cost, not cut corners)
9. Integrated infrared receiver function, easier to control playback without network.
