Design

This Amazing, Affordable, Earth Changing Device, for which no endorsement is to be inferred, is designed as a collection of layers.

  • Layers
    • Main Unit Sensor Layer
    • Audio Layer
    • Port Unit Layer
    • Processor Layer

The device is flanked by two sets of two RJ45 Socket Units. A Controls Unit is placed at one end.
