An energy harvesting circuit utilizes the right audio channel to draw power from the smart device to power the Quick-Jack board and attached sensors. The onboard joystick can be used to demonstrate a UI implementation and results are displayed by an App on the connected smartphone or tablet.
  • Header for connecting external debug probe to enable code development
