IoT Development in the Studio

The Studio development environment supports you in the development of your individual projects. The large number of sample codes, tutorials and libraries offers you a valuable start-up aid. You will receive professional IoT knowledge at first hand.

To the studio

Product configurator

You can use the runtime calculator to estimate both the autonomous runtime of the application and the associated costs. Actual costs and energy consumption depend on measurement conditions such as reception quality and ambient temperature. You can find detailed information on the tariffs here.
