What is scarab-osd?

Scarab OSD is a C-based firmware for MinimOSD-style hardware that overlays real-time UAV HUD data—like altitude, speed, GPS distance, voltage, current, and RSSI—directly onto your FPV video feed. It pulls telemetry from 15+ flight controllers (Betaflight, iNav, Cleanflight, APM, PX4, MultiWii, KISS, and more) via MSP, MAVLINK, or LTM protocols, solving the hassle of mismatched OSDs on diverse drone setups. Users get customizable layouts, alarms, map mode, and a GUI configurator for easy flashing and tweaks.

Why is it gaining traction?

With 855 stars, scarab-osd stands out for its massive FC compatibility and plug-and-play GUI that handles font uploads, sensor calibration, and layout switching without deep soldering or code dives. Pilots love the battle-tested features like glidescope for fixed-wing landings, audio vario, and ADS-B traffic awareness, all on lightweight C code that runs smooth on 8-bit AVRs. It's the go-to for avoiding vendor lock-in on pricey proprietary OSDs.

Who should use this?

FPV racers and long-range drone pilots flying Betaflight or iNav quads who need reliable on-video telemetry without FC-specific hacks. Fixed-wing builders integrating APM/PX4 will dig the GPS-based modes and efficiency meters. Tinkerers modding MinimOSD clones for custom UAVs get the most mileage from its RC switchable screens and PPM/SBUS control.

Verdict

Grab scarab-osd if you're building UAVs—its broad support and GUI make it a no-brainer over fragmented alternatives, despite the low 1.0% credibility score from sparse tests. At 855 stars and solid wiki docs, it's mature enough for production flights, but verify your hardware pins first.
