Drotek Dropix (FMUv2)
PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues.
The Drotek® DroPix autopilot is based on the Pixhawk®-project FMUv2 open hardware design. It runs the PX4 Flight Stack on the NuttX OS.
The DroPix system includes integrated multithreading, a Unix/Linux-like programming environment, completely new autopilot functions such as Lua scripting of missions and flight behavior, and a custom PX4 driver layer ensuring tight timing across all processes.
This flight controller is manufacturer supported.
