This document provides design guidelines for physical and electrical interfaces on Oculus hardware products, allowing for development of compatible accessories.
When developing Oculus Go accessories, consider the following general guidelines:
3D files and high-resolution diagrams are available for download on the Misc Packages page.
Magnetic Interference
It is recommended to avoid magnets and metal components in accessories.
Radio Frequency Performance
Materials and Coatings - Accessories should avoid the use of metal and conductive materials.
Antenna Keep-Out - Antenna keep out regions can be found on product drawings and surface files. Materials or coatings that absorb radio frequency can degrade wireless performance.
Access to Inputs and Interconnects
Access to Audio Jack and USB Connector
Faceplate
Accessories should not cover the faceplate or impact thermal performance
Acoustics
The accessory must not impair or degrade the acoustic performance
Coupling
Cases must not facilitate the conduction of sound from any speaker to any microphone
Microphone openings
Oculus Go has two microphones and both openings to the microphone cannot be blocked by the accessories. Refer to product drawing and surface files for actual locations.
Speaker openings
Oculus Go has two slotted speaker openings (one on the left strap arm and one on the right strap arm) where the sound from the integrate speakers will travel to the user’s ears. Both openings cannot be blocked by the accessories. Refer to product drawing and surface files for actual location.
Oculus Go allows for audio accessories that connect to the headset over a standard 3.5mm TRS jack.
Mechanical Specifications
Audio accessories must not detract from the visual user experience provided by the headset.
Electrical Specifications
Oculus Go is capable of driving a worst case 16Ω load at this headphone jack. The headphone jack uses a standard TRS pinout, with Left on Tip, Right on Ring, and Ground on Sleeve. No microphone capabilities will be enabled at the headphone jack. While the headphone jack is in use the standard Mic1 and Mic2 on Oculus Go will be enabled.
Straps attach in one location on the top and 2 locations on each arm. Maximum strap width is 30.0 mm.
Facial interface retention rings
3D geometry is provided for existing retention rings
Controller is not to be covered with metal or conductive material
Buttons
Input power should be designed around a 5V/2A charger supporting the Dedicated Charging Port (DCP) or Charging Downstream Port (CDP) standards in the USB Battery Charging Specification Version 1.2. When using USB OTG, the headset can supply 5V/500mA, but USB device enumeration is currently not supported.
