Why it belongs here
Raspberry Pi 5 is a Linux single-board computer whose low power use, GPIO, networking and ecosystem make it excellent for labs, sensors, gateways, small services and education.
Hardware
A 2.4 GHz quad-core 64-bit Arm Cortex-A76 CPU, USB 3, Gigabit Ethernet, Wi-Fi, Bluetooth and dual display output provide a flexible lab platform.
Good use cases
Home labs, DNS and monitoring, telemetry collection, automation, GPIO development, Linux service testing and networking education. For heavier workloads, plan power, cooling and storage carefully.
