{% hint style="info" %}
If you are adding multiple modules to the LR1 Payload at the same time, a combined counterweight is required, available [here](https://store.freeflysystems.com/collections/astro/products/lr1-payload-counterweight-boson-lrf).&#x20;
{% endhint %}

#### Software

{% hint style="success" %}
Ensure your Astro and controller are [up to date](https://freefly.gitbook.io/astro-public/maintenance/software-release-notes)! The Thermal Module is compatible with Astro firmware 1.7 and later&#x20;
{% endhint %}

Switching between cameras views can be done by tapping the camera name, or by mapping 'Next Camera' to a button on the controller

### Variants

We have shipped two variants of the thermal module. Despite the difference in lens markings, the field of view of the lenses are the same and the image quality/sensor performance is also the same. The mass is different between the two variants, which means a matching counterweight should be used to ensure good gimbal balance and stabilization.&#x20;
