# Electrical Interface

## Connector

Wiris Pro Payload uses the Smart Dovetail interface for power, data, and control. Pinouts for this connector can be found at both links bellow:

The Wiris video and control is passed through over the ethernet pins on the smart dovetail. Info on communicating with the camera can be found in the document bellow.

The gimbal utilizes Mavlink for control from the aircraft over the UART pins.

## Power requirements:

The Wiris is powered directly from the gimbal, these specs account for the entire package in operation. Power is drawn from the V\_BATT pins on the Smart Dovetail pinout.

| Voltage           | 18-25.2V                                |
| ----------------- | --------------------------------------- |
| Current (Nominal) | 0.7-1.5A depending on flight conditions |
| Current (Max)     | 5A                                      |

## 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.freeflysystems.com/ecosystem/payloads/wiris-pro-thermal/integration-for-3rd-party-applications/electrical-interface.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.
