# Developer Guide

This section provides technical documentation for developers who want to build DroneEngage from source, create custom plugins, or understand the internal architecture.


## Overview

DroneEngage is built with a modular architecture:

- **de_comm** - Communication module (connects to cloud server)
- **de_mavlink** - MAVLink module (connects to flight controller)
- **de_camera** - Camera module (video streaming and recording)
- **Plugins** - Custom modules for GPIO, SDR, tracking, etc.

All modules communicate via the **DataBus** using UDP sockets, allowing them to run on the same device or distributed across multiple devices.
