From the project

A DIY Cool looking VR Headset Compatible with SteamVR

https://github.com/HadesVR/HadesVR - All the source codes are availble in this repo and many other repos.

The pcb has a 6 pin programmer to flash the code into the atmega32u4. Additionally, a usb c is provided if a bootloader is loaded on the mcu one can directly flash to it.

A Mini DP port coming out of the dual screens display driver(Check BOM) is connected to the host pc) SteamVR can be installed on the pc and the documentation is availble here - https://github.com/HadesVR/HadesVR
