README
README.mdopenMixR 4k Mixed Reality Headset
openMixR is an open software/hardware mixed reality headset powered by an Artix-7 FPGA. It combines a high-resolution (4k) virtual reality headset with 4k cameras and a powerful FPGA to provide augmented reality experiences.
Current Status
Last year as a university group project a low resolution prototype was built, capable of demos including a 2D Minecraft game and overlaying content from an HDMI input.
PCB design for revision 1 of the 4k version - which this repo is for - has been finished and PCBs have now arrived. FPGA HDL for the cameras has been developed and tested (albeit with a different camera model only capable of 4k30, see this repo), and HDL for basic LCD functionality has been written and undergone basic testing. To run the display at 4k will require feeding it with VESA DSC compressed video; code for this is far from complete so I will be using the display at first in a mode where it upscales from 1080p - which still looks a lot nicer than a native 1080p LCD. Current LCD code is here.
I am now in the process of testing the PCBs and writing a simple AR demo using the LCD and cameras. At present no breaking issues in the rev 1.0 PCB have arisen although do take note a few minor errata points - see the hardware folder.
I am also working on a custom HLS tool, not yet released, that will be used to create much of the FPGA processing code that runs on the headset. An early version of this was used for the aforementioned low res demos.
Hardware Features
The main components of the hardware are:
- 4k LCD repurposed from Z5 premium (AUO H546UAN01.0 or unknown Sharp part) on a subassembly allowing different LCDs to be used in the future
- Dual OV16825 cameras, also on a subassembly so other cameras - in particular I am looking into the Sony IMX318 - could be used
- Artix-7 FPGA (currently XC7A200T-3FBG484E but cheaper variants could be used)
- Allwinner A64 quad-core ARM applications processor (with basic GPU for 3D rendering)
- 512MB of DDR3 attached to the FPGA and 1GB attached to the A64 processor
- WiFi and Bluetooth
- USB-C for power, data and DisplayPort video

Questions
How big is the Headset r1.0 PCB?
It measures 150 × 90 mm and has 8 copper layers, 1.6 mm thick.
What parts does the Headset r1.0 use?
715 parts, built around the TPS53316RGTR, TPS563200DDCR, STM1061N31WX6F and TPD4E05U06DQAR. 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 Headset r1.0 KiCad files?
From the daveshah1/openMixR repository on GitHub, at the commit this page was made from: the board is hardware/headset-r1.0/mainboard/mainboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Headset r1.0 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
