Ultra Low Power Modul

The M22x module is especially suitable for energy-critical ultra low power applications. Use the development environment Studio to create your individual IoT apps.

  • Based on robust and compact Mini PCI form factor
  • Long-term compatibility despite ongoing further development
  • Microcontroller and memory directly on the module
  • SIM: onboard
  • MCU: ARM Cortex M3

Flexible uplink technology

Your application runs in a VM (virtual machine), so any transmission technology can be used flexibly without porting effort.

Starter Kits

Support for the start into the IoT world

The IoT world is complex. The starter kits help you get started as easily and safely as possible. Use the M22x module in combination with one of the PoC shields with the Base Starter or with the RAW Board and you are ready to go!

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.
