## Description <a href="#description" id="description"></a>

DCS2.VTOL is a specialized extension board designed for fixed-wing and VTOL drone platforms. It combines signal extension with integrated power distribution, allowing both electrical power and control signals to be routed efficiently across the aircraft. Its design is optimized for the requirements of hybrid airframes that combine vertical takeoff capabilities with fixed-wing flight.

## Power supply

{% hint style="danger" %}
**WARNING - Do not exceed the maximum input voltage**

Exceeding the maximum input voltage of 100 V may result in permanent damage to the device. Ensure that the input voltage remains within the specified limits at all times.\
Special care has to be taken if voltage transients and oscillations are present, as these may cause the maximum rating to be exceeded. This can occur in systems with high inductance, during switching events, or when using motor controllers with active braking. Appropriate suppression and protection measures must be implemented.
{% endhint %}

{% hint style="danger" %}
**WARNING - Beware of excess heat**

Heat is generated by all onboard voltage regulators during operation, with dissipation increasing at higher load current and total power consumption. Adequate thermal management, such as airflow or passive cooling, is recommended when operating the board at higher load conditions to ensure proper thermal performance and prevent overheating.\
Onboard power monitoring can be used to provide a precise overview of power consumption across the whole system.
{% endhint %}

**Recommended Input Voltage Range:** 20–80 V

**Maximum Input Voltage:** 100 V

**Monitoring:** Input power rail is monitored and reported via CAN2 (DroneCAN)

* JET\_CAM\_SUPPLY is configurable to 3V3 or 5V by [solder bridge](#sb1) on the bottom side of the board -> SB open = 3V3 , SB closed = 5V

**WARNING**\
Pay attention to the cable pins' orientation (same/opposite side contacts). Cameras from different manufacturers can have different pin orders, so a wrong cable can cause a short-circuit!

# 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.

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

```
GET https://docs.airvolute.com/autopilots/dronecore-2/boards/expansion-boards/vtol-board.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
