System Architecture

LED Panel

Cascadable 64x64 RGB LED modules with individual pixel control and brightness calibration

Controller

STM32 microcontroller with DMA-driven LED refresh and double-buffered frame rendering

Data Engine

Node.js backend aggregating live data feeds from APIs, sensors, and custom data sources

Interaction

Capacitive touch overlay and gesture recognition for interactive content navigation

Core Capabilities

Full RGB Control

16 million colors with per-pixel brightness, gamma correction, and color temperature adjustment for sharp, accurate output.

Live Data Feeds

Real-time visualization of stock tickers, weather, social metrics, IoT sensor data, and custom API endpoints.

Touch Interactive

Capacitive touch grid overlay supporting tap, swipe, and pinch gestures for navigating content and widgets.

Animation Engine

Sprite-based animation with keyframe interpolation, particle effects, and smooth transitions at 120 FPS.

Widget Framework

Modular widget system that supports custom visualization plugins, hot-reload, and drag-and-drop layout editing.

Remote Management

Cloud-based content management system for scheduling displays, pushing updates, and monitoring panel health remotely.
