Hardware specifications for the Raspberry Pi 4 Model B include the Broadcom BCM2711 SoC with a quad-core Cortex-A72 architecture. This system provides True Gigabit Ethernet, ensuring line-rate throughput by removing the previous generation's USB-bus throttling. Memory metrics confirm the availability of various LPDDR4 capacities to manage high-memory stability for 24/7 home automation server duties.
Thermal management is required as the CPU will throttle from 1.5GHz to 600MHz upon reaching 80°C. Connectivity features include dual micro-HDMI ports for 4K output and a PoE header for Power over Ethernet compatibility. Power delivery must be managed via a 5.1V/3.0A supply to mitigate undervoltage-induced storage corruption. Data transfer is supported through native USB 3.0 ports, which allow for external SSD booting.
- SoC: Broadcom BCM2711 Quad-core.
- Ethernet: True Gigabit RJ45.
- USB: 2x USB 3.0 and 2x USB 2.0 ports.
- Wireless: 2.4GHz/5GHz 802.11ac Wi-Fi.
Utilize these open-source home automation controllers for a more resilient, pre-configured hardware stack.
The Pi 4 Model B serves as a mature alternative for 24/7 server duty where the Pi 5's higher TDP and active cooling noise are undesirable.
