Product Description

The board is a portable control module for programming light patterns, sounds, and sensor responses. Its Bluetooth connection enables wireless control of other devices or remote control from a smartphone. The integrated motion sensor detects shaking movements and orientation, while the microphone responds to volume or sound characteristics.

The processor downloads programs from a PC or browser; a dedicated development environment is not required. The web-based IDE or offline tools support programming in block-based languages or Python. Thanks to the extensive integration of sensors and actuators, no additional modules need to be wired for simple projects.

In the classroom, the board teaches beginners programming logic through visible LED effects. In robotics, it serves as a control center for small driverless models with Bluetooth motor drivers. Portable in wristbands or built into models, it can be expanded with affordable accessories into musical instruments or measuring devices.

AA batteries or a computer's USB power output are sufficient for operation. Expansion modules such as motor drivers or sensors require an additional power supply. All standard programming skills are welcome; beginners can follow the included tutorials.

Safety Information

The product is intended exclusively for building prototypes and for testing and development purposes and is not suitable for installation in the household power circuit. Consult a qualified electrician when working on or near electrical installations. Observe the polarity when powering the device with batteries and avoid short circuits at the contacts.
