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.

The development board uses the RP2040 microcontroller, you can order your own pcb as well as components to solder yourself.

This is a 24VDC to 12VDC / 500mA dual power supply project.

One of my first PCB reverse-engineering projects.The board is two-layer, with components soldered only on the TOP side.There are no components soldered on the BOT side.
