## Interfaces and Connectors

<figure><img src="/files/scIq68APzA4wdA6PEf0I" alt=""><figcaption><p>Flux interfaces and connectors</p></figcaption></figure>

**Main Interface**

This is the main connector of the LiDAR sensor that uses our Smart Dovetail connector. It is a high density industrial connector that provides power and communication to the sensor. It connects to one of our mounts or interface cables. See the Accessories sections for more information.

**GNSS Modules**

Flux requires two external Dual Full-band GNSS receivers (L1/L2/L5/L6) with active antennas to operate and achieve optimal results. These GNSS modules and cables are included with the sensor and connect to 7 pin Lemo connectors on the side of Flux.

**USB-C**

Flux captures its data as a .fluxScan file that gets stored on an external USB-C Flash Drive. The sensor comes with a 256 GB USB-C Flash Drive that allows for more than 1 hour of scanned data.

{% hint style="info" %}
Any USB-C flash drive can be used as long as it's rated for U1 speed or faster and fits into the slot on the Flux. Drives will need to be formatted as exfat
{% endhint %}

**Status LED**

The color code of this LED indicates the operational state of the LiDAR sensor and has the following meanings:

{% hint style="success" %}
Detailed status information can be shown on the Flow app on a connected iPad
{% endhint %}

**REC Button**

The REC Button start/stops the capture of the LiDAR data. When the Status LED is green, push to start recording. When the Status LED is red, push to stop recording.

{% hint style="success" %}
Recording start/stop can also be triggered from the Flow app on a connected iPad. The Flow app can only communicate with the payload on compatible systems. If using the Flux on a DJI platform, you will need to use the button on the Lidar
{% endhint %}

**Camera**

{% hint style="warning" %}
Colorization or photogrammetry is not available on Flux yet. We hope to enable this in a future software update
{% endhint %}
