Base Starter

Test board with integrated sensors

The Base Starter is a complete package for embedded developers and machine and device manufacturers. It enables easy creation and testing of IoT applications for data collection and control. At its heart is the intelligent, user-programmable M220 module.

The Base Starter supports you in the following tasks:

  • Development of IoT applications
  • Development of new web services
  • Simulation and testing of use cases

Particularly low energy consumption

The communication module is especially suitable for applications where energy consumption is a priority. A variety of microcontroller interfaces as well as wireless interfaces (WiFi, 2G/3G) are available for data exchange.

Product configurator

With the help of the runtime calculator, you can estimate the autonomous runtime of the application as well as the costs incurred. The actual costs and energy consumption depend on the measurement conditions, such as the reception quality and ambient temperature. Detailed information on the tariffs can be found here.
