Floureon On-Screen Display OSD Board MinimOSD APM Telemetry to APM 1 APM 2 APM 2.0 APM 2.5 for FPV module APM has an companion OSD board called MinimOSD. It reads all the MAVLink data in the APM telemetry stream and overlays it on the video stream if you're using an on-board camera and wireless video transmitter. This is useful if you're flying in First Person View (FPV) mode or don't want to use a laptop at the field to see your telemetry data in the Mission Planner.
