## MAVLink ##

MAVLink -- Micro Air Vehicle Message Marshalling Library.

MAVLink is a very lightweight, header-only message library for communication between drones and/or ground control stations. It consists primarily of message-set specifications for different systems ("dialects") defined in XML files, and Python tools that convert these into appropriate source code for [supported languages](https://mavlink.io/en/#supported_languages). There are additional Python scripts providing examples and utilities for working with MAVLink data.

> **Tip** MAVLink is very well suited for applications with very limited communication bandwidth. Its reference implementation in C is highly optimized for resource-constrained systems with limited RAM and flash memory. It is field-proven and deployed in many products where it serves as interoperability interface between components of different manufacturers.
