Ian thiết kế board
FiFoPi này dùng cho Pi tích hợp nhiều thứ onboard các bác .
1. Up to 768KHz full range I2S support;
2. DSD64,128,256,512,1024;
3. built-in 768KHz DoP decoder to enable RaspberryPi native DSD play back up to DSD256;
4. Isolator board will be included;
5. Clock board (isolated) will also be integrated, works with interchangeable XOs through standard sockets or adapters;
6. Supports full rang of XO frequencies from 11.2894 to 98.3040MHz;
7. Has two DC inputs for both isolated clean power and RaspberryPi power;
8. Has an additional non-isolated GPIO connector to make DAC controller working in isolated mode;
9. Works with good 5V linear power through on-board low noise LDO or pure direct 3.3V power from ulatr-capacitor or LifePO4 battery power supply;
10 Works with all RPi DAC HAT and external high-end DAC at synchronized master clock mode to remove jitter;
11. Optional external display panel with adjustable delay time;
12. DIY friendly with options and flexibility.
Lấy I2S out từ FiFoPi đưa vào I2S in của bất cứ DAC ngoài có I2S in ( Gustard chẳng hạn ) nghe DSD hoặc PCM là sướng luôn . 99$ là giá mua GB2019 bình thường là 135$ a .
Sau này có thêm board I2S HDMI này nữa lại càng đơn giản nữa .
