Pixel Driver

Eos Pixel Driver

Standalone embedded pixel control for permanent installations.

No PC. No network. No single point of failure.

The Eos Pixel Driver generates and outputs real-time lighting scenes directly on-device. Drop a scene file onto it over USB, wire it to your fixtures, and walk away. It runs at 60 fps, unattended, for years.


Built for the job site, not the server room.

Standalone Operation

No media server. No operating system. No moving parts.

Scene generation runs directly on the embedded processor. There is no Windows box in a closet to reboot, no GPU driver to update, no license server to maintain. Power it, and it runs.

Scene Loading

Drag and drop. That's it.

Connect via USB-C and the device mounts as a standard drive. Drop a scene file onto it, reset, and the new scene is running. Firmware updates work the same way — no proprietary software, no flashing tools.

External Control

Standalone, but not isolated.

Two 0–5V analog inputs accept signals from sensors, potentiometers, or control systems. The serial port accepts commands from PLCs, touch-panels, and media servers. Upstream goes quiet? The show still goes on.

On-Board Diagnostics

Read the board at a glance.

Status LEDs provide real-time feedback without tools. Power glows steady blue. Render speed reads green at 60 fps, shifting toward red under load. Input levels track from blue to red as voltage rises.

Speaks the protocol your fixtures speak.

A few of the protocols supported today. Because we own the firmware, new protocols can be added as your jobs require.

WS2812 / WS2812B

NeoPixel · TTL

Single-line addressable RGB. The most common pixel protocol in use today.

SK6812

RGBW Addressable

Four-channel output with dedicated white for warmer tones and higher CRI.

DMX512 · RS485

DMX

Full universe output via UART adapter. Compatible with legacy and high-end stage fixtures.

APA102 / SK9822

Dual-Line SPI

Separate clock and data for high refresh rates and reliable timing over long runs.

…and more on request.

Application Examples

One driver, many installations.

Permanent Installations

Set-and-forget lighting for lobbies, facades, and public spaces. Runs unattended for years.

Interactive sensor demo with addressable LEDs

Interactive Displays

Sensor-driven scenes that react to motion, proximity, or manual controls in real time.

Hybrid Control

A show controller or PLC sends high-level commands while the driver handles scene generation locally.


We design the board. We write the firmware. We build whatever the project needs.

The Eos Pixel Driver is not an off-the-shelf controller with fixed capabilities. Because Eos Lightmedia owns the full stack — hardware and software — every aspect of the platform can be tailored to your installation.
