Well this is a DEV BOARD that has 12*12 led screen ( matrix) driven by led DRIVER IS31FL3737 and controlled by RP2040 this design was the third version I made after a lot of modification ( part placements , router tweakings .... ) I tried to make it as compact as possible ( it can be more compact if made with more layers ) the matrix is driven by a I2C protocol driven by IS31FL3737

Questions
How big is the Matrix PCB?
It measures 40 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Matrix use?
190 parts, built around the RP2040 and W25Q128JVSIQ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Matrix KiCad files?
From the Az154za/SGT_SCREEN repository on GitHub, at the commit this page was made from: the board is PCB/Matrix.kicad_pcb and its schematic PCB/Matrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Matrix design in my own project?
Its repository states no licence, so its author keeps all rights: ask Az154za before reusing the design.
