# Unofficial Specifications

## Introduction

General specifications have been requested for NavQPlus. Currently there are no official qualified specifications. 

## Physical Hardware 

The CAD model below and associated measuring tools can be used to determine physical characteristics of interest. The model may also be downloaded in a variety of file formats by following the link to open in Fusion360.

## Electrical Specifcations

***PLEASE NOTE: These are unofficial specifications only. The values below may be used for guidance, but are not guaranteed.***&#x20;

### Voltage input&#x20;

* 5-20V&#x20;
* Power supplied via High voltage USB PD power switch(es)&#x20;
  * Power input and can be from **dedicated connector** or through **USB-C**

{% hint style="danger" %}
IMPORTANT: Software may be constructed which allows power from the dedicated connector to flow to the USB-C connectors **without proper and complete driver control** over the USB PD device negotiation. IF for example the USB-C connector uses a USB-C to USB-A connector, a higher voltage than is allowed on USB-A may become present. Depending on what USB A device is connected this could cause permanent damage to the USB A device.
{% endhint %}

### Power consumption

* A detailed power analysis has not been done. Below are estimates
  * Expectation is MAX 5W and typical 3W
  * 5W =\~12V\@450mA

### Enclosure dimensions

* CAD files available for board outline and case though the [link above](https://a360.co/408nS79)
* 90mmx70mm exclusive of case mounting tabs
* Tabs 82mm at max width.
* CASE Mounting tabs are 72mmx72mm
* CASE / Heatsink secondary mounting 53mmx53mm&#x20;

### Weight

* 98.4grams with Fin type heatsink attached\*
  * \* production units use a flat aluminum plate which reduce weight further

## 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://nxp.gitbook.io/navqplus/readme/unofficial-specifications.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.
