Kniwwelino® is the first micro-controller development platform entirely designed in Luxembourg for children of primary school age. The name Kniwwelino is a composition of the luxembourgish word "kniwwelen", that means to craft something, "ino" should show the deep affinity to the Arduino ecosystem and finally "Lino" as a name has a relation to lion, which is the heraldic animal of the Grand Duchy of Luxembourg.

The Kniwwelino® hardware consists of a 5x5 LEDs matrix, a RGB LED and two push buttons. There are additional ports that can be used to extend the board by additional sensors and other peripherals. The underlying micro-controller platform is also embedding a Wi-Fi stack. That enables the Kniwwelino® to connect itself to other Kniwwelino® over the Internet. By implementing standard Internet of Things (IoT) message protocols, like MQTT it could be easily be integrated in existing IoT installations.

The programming can be done with a visual programming tool in the browser. The resulting programs can then be uploaded to the Kniwwelino® via USB. For programming beginners, a website provides project and programming examples to be directly used or to be the starting point for first code modifications. After learning step-by-step the basics to programming the Kniwwelino®, the children can start implementing own ideas and share them on the Kniwwelino® platform. The small size of the printed circuit board makes it possible to embed the Kniwwelino® in nearly every crafted enclosure or object to not limit the development of the child's creativity.
