Connectivity Board

Universal, ready-to-use PCB to connect your products

Tiny chip,
many possibilities.

The Connectivity Board is a directly usable, CE-certified PCB that enables cellular connectivity for smart products as well as offline devices using LPWA and OMA LwM2M. Our board comes with a embedded MFF2 SIM, which provides access to Vodafone's global Narrowband IoT/LTE Cat M1 network. This guarantees a secure and reliable connection, even in remote locations or basements.

The mainboard contains the Nordic Semiconductor nRF9160, which covers a wide range of use cases out of the box and is also expandable via daughterboards. The Connectivity Board can be installed directly in existing products or equipped with the help of a retrofit. It also fits into protected and standardized Bopla cases.

Nordic nRF9160

At the heart of the board is the Nordic nRF9160 chip with Arm Cortex-M33 processor and integrated NB-IoT and LTE-M modem.

MFF2 SIM

In cooperation with our parent company Vodafone, we provide an already configured MFF2 SIM with our Cellular IoT Offering.

CE-certified

The Connectivity Board is CE certified and therefore suitable for use within Europe.

Expandable

For your specific applications, our Connectivity Board can be easily and flexibly extended by various daughterboards.

    For industrial environments

    The PLC Daughterboard is a fully isolated 5x 24V digital in, 5x 24V digital out expansion board which shall be used in industrial environments.

    The isolated digital inputs and outputs are read and written via a SPI interface. In addition to the digital I/Os, an external supply voltage of 24V has to be converted to a voltage of 12V which supplies the Connectivity Board (VBAT is used to power the mainboard from the daughterboard).
