# ARK Just A Jetson

The ARK Just A Jetson (JAJ) is a compact carrier board for the NVIDIA Jetson Orin NX/Nano module. It provides essential connectivity including USB-C, Ethernet, WiFi/Bluetooth, CSI camera, CAN bus, and GPIO in a minimal form factor.

## Where to Start

**Your bundle arrived preflashed.** It already runs ARK-OS. Go to [Set Up Your Jetson](/products/embedded-computers/ark-just-a-jetson/setup.md), then manage it from the ARK-UI web interface.

**You have a bare board, or you want to flash it yourself.** Install a Jetson module and NVMe SSD, then start at the [Flashing Guide](/products/embedded-computers/ark-just-a-jetson/developer/flashing-guide.md).

## Sections

* [Set Up Your Jetson](/products/embedded-computers/ark-just-a-jetson/setup.md) — connect to it and get it on your network
* [Using ARK-OS](/products/embedded-computers/ark-just-a-jetson/using-ark-os.md) — the preinstalled services and web interface
* [Hardware Reference](/products/embedded-computers/ark-just-a-jetson/hardware.md) — pinout, GPIO, cameras, onboard sensors
* [Developer Guide](/products/embedded-computers/ark-just-a-jetson/developer.md) — flashing, serial console, building from source

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.arkelectron.com/products/embedded-computers/ark-just-a-jetson.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
