Raspberrypi 3 raspberrypi 3 2 alternative HIFI DiGi digital sound card I2S SPDIF
specialDo not declare: This product linkWithout raspberry circuit board and Digi housing.
Support the latest 64-bit raspberry pie 3B, has been tested, please rest assured to buy! . . .
Integrated infrared receiving function Teaching:Expansion board and raspberry pie 3 generations, 2 generations are no welding, can be used directlyThis is a dedicated HIFI Digi expansion board (PiFi Digi ) for the Raspberry 2 B-type, B / A design using Wolfson's high-end digital chip (WM8804G), using the I2S interface, a non-USB interface; After the board, users can set up their own network HIFI player with the audio playback system (such as volumio, xbmc system, etc.). The expansion board provides optical fiber (S / PDIF) and coaxial (RCA) two output interfaces to facilitate external amplifier and other equipment. With it you can get rid of PC power consumption, power on slow, power supply noise and so troubled. . . . Features:1. Digital chip using Wolfson's high-endOf the WM8804GChip, with I2S interface; support for 16 to 24-bit audio data format; distortion and dynamic are very good to support the high 192kHz sampling rate, advanced technology can shake down the inherent jitter (Intrinsic period jitter) control within 50ps RMS , High degree of reduction.\
2. Output port using optical fiber and coaxial two kinds of interface output, user-friendly external amplifier
3. Support hardware mode control volume (I2C interface)\
4. Power supply using raspberry power supply, no external power supply; and the use of π-type filter power supply design, effectively reduce the power supply interference
5.I2S interface with direct digital output, high degree of reduction, non-USB interface, DAC mode, not taking up other extended raspberry raspberry\
6. Power indicator light, easy to observe the expansion board status
7. PCB board on the high gold-plated process, arc traces (high-end HIFI DAC are used arc traces), the better to ensure signal continuity of the impedance and reduce the signal reflection and refraction.\
8. Good sound depends on the real material, fiber optic interface using imported HIFI-class high-quality fiber optic cable, coaxial interface is used Pluse imported audio isolation transformer in providing good digital audio at the same time very good to protect your audio equipment and boards . . . (Similar foreign products have been removed in order to cost, in order to sound a good reliability in order we will not begrudge the cost, not jerry)
9. Integrated infrared receiver, in the absence of network, more convenient to control playback.\
