From the project

KiCAD EDA automatic component placement tool

Current LED matrix displays are underwhelming: low brightness, low dynamic range, and washed‑out visuals in real venues. Hyperion flips that on its head with ridiculous luminance, high refresh, and a visual language that holds up in fog, dark, and daylight spill.

- Blinding brightness: designed to punch through haze and stage lighting - High refresh: > 500 Hz target for artifact‑free motion and strobes - Chunky pixels: 4 LEDs per pixel, 15 mm pitch for bold geometry - Modular: building full 420 × 420 mm panels (limited by JLC assembly) - Controls: video stream input (WIP) + DMX for…

Demomatrix: common questions

What microcontroller does the Demomatrix use?

The Demomatrix is built around the RP2040, from the RP2040/RP2350 family.

How big is the Demomatrix PCB?

The Demomatrix measures 10.8 × 7.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Demomatrix?

1591 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Demomatrix design files?

From the glovepost/atoplace repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Demomatrix design in my own project?

Yes, under the terms of its MIT license, which glovepost chose for the repository.

Can I test firmware for the Demomatrix without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
