Datasheet Release 1.2

Remote monitoring of critical infrastructure with edge computing
================================================================
The nRF91 Connectivity Cards from CTHINGS.CO® are extension cards based on the Nordic® Semiconductor nRF9161 SoC. They are multi-protocol chips designed to empower IoT integrators to implement DECT NR+, LTE Cat-M1/NB1/NB2 protocol stacks.
The extension card allows for full-fledged utilisation of the on-board Arm® Cortex®-M33 CPU with FPU. In addition, the ARM TrustZone® CryptoCell 310 cryptographic unit brings an extensive range of cryptography options.
The product comes with full CE class-B and RED certification and can be used to quickly and reliably add LTE or DECT NR+ protocol stack support to any existing device with an M.2 without worrying about certification or radio performance. A full J-Trace connector is available on a programming jig for convenient firmware development.
CTHINGS.CO also provides various pre-flashing options, and tested support for Wirepas 5G Mesh firmware profile.
