NORVI Expansion Modules provide the flexibility to extend your device’s capabilities for advanced IoT and industrial applications. Designed for developers and system integrators, these modules seamlessly integrate with NORVI controllers for enhanced performance.
There are three types of NORVI expansion modules to meet diverse requirements:
LoRaWAN Expansion for long-range wireless communication
NB-IoT Expansion for narrowband cellular connectivity
Analog Input Expansion for precise sensor data acquisition
These add-ons simplify the development of scalable, high-performance IoT systems in smart environments.
LoRa communicaon module with the RYLR896 transceiver provides ultra-long range spread spectrum communicaon and high interference immunity whilst minimising current consumpon. The module is cerfied by NCC and FCC.
Nb-IoT communicaon module with the BC95-G provides ultra low power communicaon interface for NORVI controllers. The module supports the global bands making it applicable around the world with a super high sensivity.

LoRa (Long Range) technology excels in providing long-range communication capabilities, making it ideal for projects that require connectivity over large distances or in areas with limited infrastructure. NB-IoT (Narrowband IoT) operates on existing cellular networks and offers better coverage in urban areas but may have limitations in remote or rural locations.
NB-IoT typically consumes less power compared to LoRa, making it suitable for battery-operated devices or applications where power efficiency is critical. LoRa, on the other hand, is more suitable for applications where power consumption is less of a concern, but long-range communication is essential.
LoRa provides higher data rates and bandwidth compared to NB-IoT, allowing for faster transmission of large volumes of data. If your project requires high-speed data transfer, LoRa may be the preferred choice. However, NB-IoT’s lower data rates are often sufficient for applications that involve periodic transmission of small data packets, such as sensor readings.
LoRa operates in the unlicensed ISM (Industrial, Scientific, and Medical) bands, which may be susceptible to interference from other devices operating in the same frequency range. NB-IoT operates on a licensed spectrum, providing better immunity to interference but requiring compliance with cellular regulations and potential subscription costs.
Analog input expansions allow for direct interfacing with analog sensors, making them suitable for projects that require integration with a wide range of analog sensors without the need for additional digital conversion hardware. However, LoRa and NB-IoT modules may require additional sensors or interfaces to connect to analog sensors, adding complexity and cost.
LoRa modules and infrastructure may have lower upfront costs compared to NB-IoT, as LoRa operates on unlicensed spectrum, reducing the need for expensive cellular subscriptions or infrastructure. Analog input expansions, depending on the specific components and implementation, can offer a cost-effective solution for projects with simpler requirements or budget constraints.
