# HW Control

Through the **hardware menu** of the main window you can access panels to show / control every LTT standard hardware.

A LTT usually comes with the following standard hardware:

* [power supplies](/ltt/documentation/ltt-gui-manual/lttgui/hwcontrol/ps-control-gui.md) (for the DUT's)
* [temperature sensors](/ltt/documentation/ltt-gui-manual/lttgui/hwcontrol/ts-control-gui.md) (for climatic chambers)
* [temperature chamber contact](/ltt/documentation/ltt-gui-manual/lttgui/hwcontrol/tcc-control-gui.md) (digital I/O)

{% hint style="info" %}
You have to configure the LTT standard hardware in [module configuration file](/ltt/documentation/ltt-gui-manual/configuration/moduleconfiguration.md).
{% endhint %}
