M22x

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.

Product features

  • Very low energy consumption
  • SPI, UART, I2C and GPIO interfaces
  • Hardware Real-Time Clock
  • Programmable via script language
  • APIs for:
    – Date, time and timer
    – I/O, SPI, I2C and UART
    – Interrupts
    – Communication
    – External SIM
    – Measurement, log and configuration data
    – File transfer
    – Positioning
    – SMS reception
    – Measurement of operating voltages (VIN,
    VAUX)

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’re ready to go!

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.
