1. Model 1A/1A+ - Using a Y-cable to provide more power to the display

A Y-cable helps deliver more power to the display when the computer USB port (such as a laptop) cannot provide the necessary power.

  • Model 2A has an extra power port on the outside of the enclosure therefore a Y cable is not needed.
  • Model 1A+ has an extra power port inside the enclosure on the LCD board which can be used as an alternative to the Y-cable.
