Bring output from other synthesizers, samplers, or any audio source to Eurorack signal levels. Ready for endless creative processing.

The project is an electronic board for operating an LED array. This is a complete PCB project for managing an LED array, including a professional printed circuit board design with all the files required for manufacturing, assembly, and documentation. The circuit allows for arranging and operating multiple LEDs, and is suitable for use in display systems, smart lighting, educational, and DIY projects.
