# Getting Started The Jetson OS and flight controller firmware both come pre-flashed when you order. We flash the latest version of our Jetson kernel and the latest version of PX4 stable.\ \ You can ssh into your Jetson via the USB C cable. The username and password are both **jetson**. ``` ssh jetson@jetson.local ``` If you purchased a bundle the [ARK-OS](https://github.com/ARK-Electronics/ARK-OS) comes pre-installed. Please see the [ARK Software](broken://pages/AvsoDtZlpuV5w8m178Nc) section. You can also re-flash your Jetson using our [ark\_jetson\_kernel](https://github.com/ARK-Electronics/ark_jetson_kernel) repository to ensure you're running the latest OS. You can find more instructions for re-flashing the Jetson in our [Flashing Guide](/products/flight-controller/jetson-pabs/ark-jetson-pab-carrier-v3/flashing-guide.md). --- # Agent Instructions: 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.
