EdgeTX Developer Documentation¶
Welcome to the EdgeTX developer documentation!

EdgeTX is an open-source firmware for RC radio transmitters. This documentation covers technical topics for developers and contributors: how to build EdgeTX from source, hardware reference material, hardware modification guides, and internal software architecture.
What's in this documentation¶
- Contributing — Getting started with Git, the GitHub workflow, and a command reference for common Git operations.
- Building EdgeTX — Step-by-step build instructions for every supported platform (Linux, macOS, Windows, Docker, and GitHub CodeSpaces), plus a reference for all CMake compilation options.
- Hardware Reference — Radio hardware specifications, DMA mappings and IRQ usage tables for specific radios.
- Hardware Mods — Community hardware modification guides for FlySky gimbals, FRM303 module, PL18 / Paladin EV, NB4+, and radio recovery (unbricking).
- Development — Internal architecture documentation covering CLI commands, customisable switches, control inputs, external module protocols, YAML storage, and mixer synchronisation.
