**Post here if:** You are working with Raspberry Pi, Orange Pi, RockPro, or any integrated board running a full OS (Linux/ARM). **Topics include:** Server setups (like our CyberWars Pi Zero), GPIO pin hardware interfacing, headless OS configurations, thermal management, and Pi-specific networking (Tailscale, Nginx). *Note: If your project uses an Arduino or ESP32 (no full OS), put it in Microcontrollers.*
