Digital Expansion Board IS HDMI Optical Fiber Coaxial Output for Raspberry Pi 4B Support DSD64 128 256 512

Description:
- This model supports the latest version of Raspberry Pi4B; it supports Pi2B+, Pi3B, Pi3B+, Pi4B
This is a special HIFI Digi+expansion board (PiFi Digi+) designed for raspberry pie 4B/3B+/3B/2 B, B+/A+. It uses for Wolfson's high-end digital chip (WM8804G), and uses I2S interface, not USB interface; After using this expansion board, users can build their own network HIFI players with audio playback systems (such as volumio, moode systems, etc.); The expansion board provides optical fiber (S/PDIF) and coaxial (RCA) output interfaces to facilitate external power amplifier and other equipment. With it, you can get rid of the problems of high PC power consumption, slow startup and shutdown, and loud power noise.

Support output:
- Coaxial output
- Optical Fiber support 192KHz output
- HDMI I2S output (default A mode as figures below)

 

Quick Operation Guide:
- After receiving the product, please do not power on and test it immediately. Please connect all signal wires first, then connect the power cord. (Color) will see the panel PWR (red Raspberry Pi power-on power indicator) (if it is a constant temperature crystal oscillator board, it will take about 20 seconds to warm up before the indicator light.), continue to wait for about 5 seconds ACT (green channel indicator light) A flash.) It proves that it is booting, wait for about 20-30 seconds to complete the boot.

Enter the system operation instructions:

- Power on successfully, enter the router "terminal management" to find the IP named "dhcpcd-*.*.*-armv71" (* represents the firmware version of the network card, which may not be the same for every Raspberry Pi version.), with "192.168. 2.225" is the column, enter "192.168.2.225" in the browser to confirm to enter the operating system control terminal.

Indicator light description:
- ACT is the channel indicator, which usually flashes only after the network is successfully connected. PWR is the power indicator of the Raspberry Pi. The normal indicator of the Raspberry Pi is always on (Some Raspberry Pi will turn off after successful startup, but no reason is found), the orange non-Gigabit LAN indicator light and the green non-100M indicator light on the network card port on the back of the data broadcast.

Play output DSD, DTS description:
- Currently testing Volumio and Moode systems, DTS, DSD16, DSD32, DSD64, DSD128, DSD256, DSD512 output can be played normally in DSD direct output, but the decoder support is required. I use AKM4495, AKM4497, AKM4499, ES9038 Q2M. The output can be played normally, if there is no sound output, please check the decoder by yourself.

Features and function:
- Support for Volumio system and for Moode system
- Support mobile platform: for Android, for IOS, for Harmony OS
- Support file format: FLAC, APE, DTS, AC3, WAV, DSF, DFF, MP3 and so on.
