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

> You have to configure the LTT standard hardware in [module configuration file](/en/docs/ltt/documentation/ltt-gui-manual/configuration/moduleconfiguration).
