This digital board is an upgraded version of the 2017 HIFIDIY collaboration version（ http://bbs.hifidiy.net/thread-1264026-1-3.html )
This modification is quite significant. It took three samples to be made before the correction was completed. The modification time was quite long. Thank you very much for your patience
This version uses a 4-layer board design, 2mm, gold plating process processing, optimized wiring, updated display module, and supports multiple input interfaces
The motherboard has a balanced coaxial fiber USB input interface (reserved for Amanero card standard)
Extended E-board supports BNC (RS422/TTL) ST fiber HDMI (A/B mode, requires soft control settings)
It is expected that a firmware refresh interface will be opened, which can support more DACs such as PCM63 and PCM1704 through different firmware
The display button interface of the motherboard adopts serial communication, which makes it convenient to design your own display panel
The display board for the group buying chassis is expected to be designed, using 3.12OLED. Please stay tuned ....

The size is 10x20cm, and the detailed information will be updated later
