Display Node Core Architecture

[MFelida]

Description: Design and implement the core architecture for display nodes with modular design.

Tasks:

• Define hardware platform for display nodes (Most likely also RPi PICO)
• Design modular software architecture
• Implement MQTT client for subscribing to sensor topics
• Create data aggregation and processing layer
• Design plugin/module interface for custom displays
• Implement configuration system (which sensors to monitor, display preferences)

Deliverables:

• Display node architecture documentation
• Core firmware framework
• Module interface specification
