Overview
Matrix is an open-source printed circuit board by makerio90, from the makerio90/VOLUME_DISPLAY repository on GitHub. It is a 4-layer board of 82.3 × 50.9 mm with 513 parts on 48 nets, routed with 1,458 tracks and 518 vias.
It is built around the SML-D12U1WT86. Its parts include 512 diodes and 1 connector. It belongs with the lEDs and displays boards of this library.
Main components
1README
README.mdVOLUME_DISPLAY
this is a project i have been working on for the better part of a month now, this is only the first commit as i have dicided to add the project to github.
The Idea:
i wanted to make a volumetric pov display. i got insperation from these projects:
both work off of the same principle: phisicly rotating an led matrix to create the sense of volume.
this seemed doable so i started work on schematics.
theory of operation
cutting to the chase here: this is what the mainboard needs to do:
the main board is intended to drive a 32x16 led matrix at a high framerate (>1000fps). new frames will be added to a framebuffer through a rs-485 bus. 12v power will also be supplied. a hall effect sensor will provide a sync signal, allowing the board to make minor ajustments to its framerate. most importently, this whole board rotates around. 12v and rs485 is fed through a slipring.
the entire board must be slowed to a stop in order for the rp2040 to be programmed. whenever the usb port is plugged in. the rp2040 will be powered and in prog mode. the led drivers should be off when usb is plugged in!
the board will be in the shape of a circle. the led matrix will be mounted vertically in the center via the attached pinheders. because the board will likely be unbalanced, nuts and bolts will be added around in a circle to provide an option for balance.

Questions
How big is the Matrix PCB?
It measures 82.3 × 50.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Matrix use?
513 parts, built around the SML-D12U1WT86. 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 makerio90/VOLUME_DISPLAY repository on GitHub, at the commit this page was made from: the board is Matrix/Matrix.kicad_pcb and its schematic Matrix/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 makerio90 before reusing the design.
