# Integration

The following pages contain dedicated instructions for integrating necessary components for GOBI with a variety of sufficiently tested aircraft.

GRYFN Gobi integrates the Freefly Smart Dovetail for both mechanical mounting and electrical connection on all aircraft integrations. Developed by Freefly, in conjunction with Pixhawk, to become the new standard for payload mounting with Pixhawk Payload Bus interfaces, used on nearly all Pixhawk and Ardupilot based flight controllers. 

Please see Freefly's own words below, but do note that this dovetail is not hotswappable. Therefore, the payload should be attached to the aircraft before being powered, and not removed from the aircraft until after power is turned off.

{% hint style="danger" %}
No hotswap protection. Do not mate or demate Smart Dovetail while the aircraft is powered.

If the payload has even modest capacitance or other inrush current the connector contacts on both aircraft and payload side will be eroded.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://gryfn.gitbook.io/gryfn-hardware/support/gobi-user-manual/integration.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
