Moto Mods are hardware enhancements

  • Snap seamlessly to the rear of the Moto Z
    • Magnets provide a strong attraction
    • Hotplug, no reboot needed
  • Provide a wide variety of interfaces to enable 3rd party creativity
    • Enhance existing functionality, like battery life
    • Introduce entirely new features
  • Tight integration into Android OS
    • Utilize standard behaviors and interfaces
    • SDK to allow for unique experiences

Mechanical

Fixed dimensions for future generations ensure compatibility.

 

  • X/Y dimensions of Moto Z
  • Size, placement, and layout of the Moto Mods Connector
  • Size, placement, and cone angle for the Moto Z camera
  • Placement of the magnets for connection
  • Antenna keep-out areas to ensure performance.
