This is the Interface board for radxa cm5.
This board contains VL805 PCI to USB hub, CS42L42 audio codec, DSI, HDMI, Ethernet, USB, microSD and GPIO connectors. This board is developed for embedded applications, so the connectors
Special connectors
- USB connectors are special but available for purchase (MCS-PN-R100-110-55-LR-IPX).
- HDMI is compatible with waveshare 20 pin HDMI connector.
Problems and tests
See TODO.md file for more details
- USB3 and VL805 works well but appropriate firmware should be loaded into flash. The diode should added for good operation.
- Ethernet has not been tested.
- The biggest Inductor should be changed to B82477R4562M100 for better performance.
- CS42L42 do not work yet. I can see it by i2cdetect but cannot read the register values. I do not know where the problem is.

Questions
How big is the Interface PCB?
It measures 110 × 57 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Interface use?
211 parts, built around the TPS62823DLC, SIC438BED, TPD4E05U06DQAR and TPS2061DBV. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Interface KiCad files?
From the Shisius/EyeMeterPCB repository on GitHub, at the commit this page was made from: the board is Interface/interface.kicad_pcb and its schematic Interface/interface.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Interface design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
