Description of the Kniwwelino Hardware and Website

The Kniwwelino hardware is a micro-controller development platform that includes a board and a visual programming tool (Kniwwelino Blockly) adapted for kids and an Arduino library. The Kniwwelino hardware consists of a 5×5 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 Kniwwelinos over the Internet. By implementing standard IoT message protocols, like MQTT it could be easily be integrated in existing IoT installations. 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.

The Kniwwelino website ( provides project and programming examples to be directly used with the Kniwwelino hardware or to be the starting point for first code modifications. It gathers also projects provided by the Kniwwelino users.
