Sd Card For Raspberry Pi Media Centers
-
Product Highlights- After using this expansion board, user can coordinate with the broadcast system (volumio，xbmc system etc.) to set up your own hifi player network
- Updated dac chip with bbti company’s pcm5122 chip. it has i2s port and you can use the i2c port to control the volume and the frequency parameter. it support 16 to 32 frequency data format. distortion and dynamic condition are very ideal. it supports the high 384 khz sampling frequency and dynamic range is 112db with distortion factor -93db
- Pifi digi / dac+ / hifi digital audio card pinboard for raspberry pi 3 2 model b b+
- Pcm5122 dac chip and i2s interface, perfectly compatible with the official raspberry pi pi hat size, pcb board with gold plating on the tall, curved traces (high-end hifi dac are using curved alignment), to better ensure the continuity of the impedance signal to reduce signal reflections and refractions
- With isolated power design, the raspberry pi power and dac part of the independent power supply are isolated. common ground without disturbing each other through the beads, it can get rid of the current sound.
