Seluxit A/S BBC Micro:bit Add-on Wappsto:bit NB IoT+ SLX W11 003

Seluxit A/S SLX W11 003 BBC Micro:bit Add-on Wappsto:bit NB IoT+ is a specialized expansion board designed to bring wireless connectivity and enhanced sensor functionality to the BBC Micro:bit educational microcontroller platform. This adapter facilitates connection to Wi-Fi and mobile networks via its integrated NB-IoT modem, expanding the microcontroller's data communication capabilities for project development in IoT and smart sensor applications.

The board converts the BBC Micro:bit's GPIO bare contact pads to standard 2.54 mm pitch pin strips compatible with Arduino and related development boards, providing accessible interfacing for peripheral modules. Each GPIO signal line is supplemented with dedicated 3.3V and ground pins, enabling stable and versatile sensor connectivity without exhausting available power lines.

Central to its connectivity is the Quectel BC66-NA NB-IoT modem, which supports narrowband IoT communication with an onboard SIM slot, allowing devices to connect to mobile networks for remote data transmission. This feature is complemented by a status LED which signals connection status to the Wappsto platform by Seluxit, simplifying troubleshooting and network management.

With a micro USB power input supporting an operating voltage from 4.5V to 5.5V, the module is easy to power from common USB sources. A dedicated button is provided for resetting network settings, facilitating seamless reconfiguration during field deployment or development cycles.

Manufactured in Denmark, the Wappsto:bit NB IoT+ is ideal for STEM educational environments, IoT researchers, and developers requiring robust low-power network connectivity on the BBC Micro:bit platform. It supports usage in industrial, laboratory, educational, and prototype IoT development scenarios, making connected sensor experimentation accessible and scalable.

The expansion board enables Wi-Fi and mobile network connectivity through NB-IoT modem integration. Compatible with the British learning microcontroller BBC Micro:bit, it converts GPIO bare contacts to Arduino-compatible pin strips.

Supports 3.3V sensors with dedicated 3.3V and GND pins for each signal line. Equipped with Quectel BC66-NA NB-IoT Modem featuring a SIM slot for cellular communication. Includes status LED for connection indication and a button to reset network settings.

Powered by micro USB, operating voltage ranges from 4.5V to 5.5V. The edge connector allows secure attachment to the micro:bit, enabling seamless integration. Designed and manufactured in Denmark with a focus on STEM education and IoT development.
