MWOSD (scarab-osd) is an open-source multipurpose on-screen display (OSD) firmware for UAVs and FPV drones, written in C for Arduino-compatible hardware. It renders a heads-up display of flight telemetry (voltage, GPS position, altitude, speed, RSSI, timers) and supports many flight controller stacks including Betaflight, iNAV, Cleanflight, APM, PX4, and MultiWii.

Use cases

• overlay flight telemetry on FPV video with an OSD
• display GPS altitude, direction, distance and speed on a drone HUD
• show battery volts, amps, RSSI and flight timer on screen
• configure OSD firmware for Betaflight or iNAV flight controllers
• run a groundstation OSD for link voltage, RSSI and timer
• flash OSD firmware easily via a GUI configurator

When to choose

• you fly FPV with a MAX7456-based OSD board and a supported flight controller like Betaflight, iNAV, APM or PX4
• you want a mature, widely supported open-source OSD with configurable layouts
• you need GPS-based telemetry overlays for long-range or fixed-wing flying

When to avoid

• you need OSD for a flight controller stack not in the supported list
• you want a closed-source turnkey OSD with vendor support
• your hardware is not Arduino/AVR-based or lacks a compatible OSD chip
