External RGB LED Status Indicator USB Module for Pixhawk Flight Controllers

A Pixhawk's built-in status LED is genuinely useful for reading arm state, GPS lock, and failsafe conditions at a glance - right up until the flight controller ends up mounted somewhere inside a canopy or stack where that LED is no longer visible from outside the aircraft. This module solves that specific problem by relaying the same RGB status signal out through a USB connection to an externally-mounted indicator, so a pilot doing a pre-flight check can still read arm/GPS/failsafe status without needing to crack open the airframe first.
