1.Description:
-
It is a HIFI DAC expansion board.This is a special expansion board designed for Raspberry Pi B+.
-
It used DAC chip (PCM5122), I2S interface, non-USB interface, and can support hardware control volume.
-
After using this expansion board, users can cooperate with audio playback systems (such as: volumeio, xbmc system, etc.) to build their own network HIFI players, the expansion board provides 2 types of output interfaces for external power amplifiers and other equipment.
-
It is not recommended to push the headset directly,it may damage the product and the headset.
2.Feature:
1>.It supports 32Bit data
2>.It supports up to 384K data sampling rate
3>.The output port uses gold-plated RCV dual terminals and gold-plated 3.5mm headphone socket
4>.The isolated power supply design is used to isolate the Raspberry Pi power supply from the independent power supply of the DAC part,and the magnetic ground can not interfere with each other to get rid of the current sound.
5>.No soldering,just plug in the expansion board,and use I2S interface to decode digital to analog,non-USB interface DAC.
6>.Added status display for bi-color LED,red light is DAC power indicator (power is on normally),green light is DAC working status light (on when working is decoded,off or off when not working),to better understand the work of DAC Happening.
7>.Perfectly compatible with the official PI HAT size of the Raspberry Pi,which can better ensure the continuity of the impedance of the signal and reduce the reflection and refraction of the signal.
8>.It provides infrared receiver interface
