## What it is
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

## Facets
