# Set Up Your Carrier

## What's Pre-Installed

Bundles ship ready to use — no flashing required:

* **Jetson**: Latest ARK Jetson image (JetPack 6 / L4T r36) on the NVMe SSD, with [ARK-OS](https://github.com/ARK-Electronics/ARK-OS) pre-installed
* **Flight Controller**: Latest PX4 stable firmware
* **Credentials**: Username `jetson`, password `jetson`, hostname `jetson`

{% hint style="info" %}
The default password is well known — change it (`passwd`) before putting the vehicle on a network you don't control.
{% endhint %}

A bare carrier board (no Jetson module or SSD) has no OS on it. Install your module and NVMe SSD, then follow the [Flashing Guide](/products/flight-controller/jetson-pabs/ark-jetson-pab-carrier/developer/flashing-guide.md).

## Steps

1. [Connect](/products/flight-controller/jetson-pabs/ark-jetson-pab-carrier/setup/connect.md) — reach the Jetson over Micro USB, WiFi hotspot, or Ethernet.
2. [Get Online](/products/flight-controller/jetson-pabs/ark-jetson-pab-carrier/setup/get-online.md) — join it to your WiFi network.
3. [ARK-OS](/software/ark-os.md) — the preinstalled services and the ARK-UI web interface.
4. [Autopilot Connections](/products/flight-controller/jetson-pabs/ark-jetson-pab-carrier/using-ark-os/autopilot-connections.md) — connect QGroundControl or Mission Planner.

## 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://docs.arkelectron.com/products/flight-controller/jetson-pabs/ark-jetson-pab-carrier/setup.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.
