Our NB-IoT Development Board and NB-IoT Demo Kit enable your use cases to be realized efficiently and in product-quality. Using our NB-IoT Relay Service (NRS), you can then easily and securely link your NB-IoT devices to the Cloud platform of your choice or your proprietary backend – on the device itself via UDP, on the network side via either HTTPS or Socket.IO. Thanks to the embedded software library supplied with all boards as standard, configuration is completed in next-to-no-time. You can carry out further settings as well as device and user management conveniently at any time via the web interface.

    With the Demo Kit, you can gather first experience with NB-IoT in an easy way. At the same time, e.g. for management sessions, an initial proof-of-concept for your own use cases can be realized in just a few hours, thereby contributing a tangible component to your internal discussion.

    The core component of the Demo Kit is the Tuino096 Development Board from Gimasi, which is equipped with an NB-IoT module (Quectel BG96) and can be programmed using the well-known Arduino development environment (C and C++). A sample code and a detailed manual for commissioning your demo kits is available to you on our Github page.

    The all-in-one for the quick & easy realization of IoT demonstrators

    WIS NB-IoT Demo-Kit

    • Features diverse sensors and actuators from the Seeed Groove portfolio (temperature & humidity sensor, ultrasonic sensor, light sensor, OLED display, GNSS antenna)
    • 118 other sensors with plug-and-play integration capability
    • SIM card with 25 MB NB-IoT data volume (6 months validity)

    NB-IoT Relay Service

    The choice of provider for IoT connectivity often also involves being tied to its platform, protocols and interfaces, because the secure transfer of data flows from a UDP-based sensor network to a TCP-based computer network requires a protocol translator, which is usually implemented by the provider concerned.

    With our NB-IoT Relay Service (NRS), YOU choose the platform: The NRS supports a wide range of communication protocols (UDP, HTTPS, Socket.IO, CoAP, MQTT, etc.) and therefore enables a connection to a variety of Cloud platforms or proprietary systems to be made quickly and easily, while retaining the advantages of specific protocols at the sensor or computer network side (energy-efficiency and security). Including devices and user management, of course, very simply via GUI.

    You make the platform decision, we deal with the connection

    WIS NB-IoT Relay Service

    • Easy and secure connection of your NB-IoT devices to a variety of IoT platforms, Cloud services (e.g. Azure, Adafruit) or proprietary backends
    • Web interface (GUI) for the administration of users and devices
    • Conversion of data flows from the sensor in computer networks while retaining the protocol-specific advantages at both sides (energy-efficiency, security)
