## What it is
An open-source firmware for a DIY 2.4GHz multiprotocol transmitter module that lets almost any RC transmitter control many different receivers and models. It supports a wide range of protocols for helicopters, planes, quadcopters, and miniquads.

## Use cases
- control multiple brands of RC receivers from one transmitter module
- fly quadcopters and miniquads with a single TX module
- bind a transmitter to different receiver protocols
- build a DIY 4-in-1 RF module for an RC radio
- update multiprotocol firmware and multi.lua scripts on EdgeTX radios

## When to choose
- you want one transmitter module to speak many RC protocols
- you fly mixed fleets of planes, helis, and quads from different brands
- you want an open, community-supported alternative to brand-locked RF modules

## When to avoid
- you need a plug-and-play commercial module with vendor support
- you only use one proprietary protocol and don't want DIY hardware
- you are not comfortable flashing firmware or soldering hardware

## Facets
- artifact type: application
- maturity: active
- function: embedded, sdk, developer-tools
- domain: hardware, embedded-systems, gaming-tools
- platform: embedded, cpp, cross-platform
