# ARK FPV

The ARK FPV is a flight controller based on the [ARKV6X](/products/flight-controller/arkv6x.md) in a 30.5 mm mounting pattern, with an [STM32H743IIK6](https://www.st.com/en/microcontrollers-microprocessors/stm32h743ii.html) MCU, an [Invensense IIM-42653](https://invensense.tdk.com/products/smartindustrial/iim-42653/) industrial IMU, a [Bosch BMP390](https://www.bosch-sensortec.com/products/environmental-sensors/pressure-sensors/pressure-sensors-bmp390.html) barometer and an [ST IIS2MDC](https://www.st.com/en/mems-and-sensors/iis2mdc.html) magnetometer. It takes 3S–12S battery input and has a regulated 12 V 2 A output for video transmitters and payloads. It ships with PX4 and also runs ArduPilot and Betaflight. USA built, NDAA compliant and [Blue Framework listed](https://tyrionprod.servicenowservices.com/gsp?id=framework_list).

# 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/flight-controller/ark-fpv.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.
