Onboard Display

This article explains how to connect a small onboard display to a flight controller which can be useful for displaying a small amount of vehicle information before takeoff.


This information includes:

  • arming failure messages
  • flight mode
  • battery voltage
  • GPS Lock and satellite count
  • Pre-arm passed/failed
  • EKF status


Support for the onboard display is included in Copter-3.5 (and higher).
