SSH alone is insufficient for embedded Linux development once boards live in remote racks or shared labs. The post outlines the core requirements for a proper board farm: out-of-band serial console access (UART) for visibility into bootloader and kernel output, remote power cycling and boot mode control for recovery without physical presence, scripted reimaging to restore a known-good state, and log capture for unattended test runs. A hobbyist setup using a Raspberry Pi 5, USB serial adapters, smart plugs, and open-source tools can cover most of these needs on a small budget. At larger scale, commercial console servers, managed PDUs, and lab management software become worthwhile. Optional smart-home integration (Home Assistant, Tasmota) can add monitoring and automation on top of these primitives.
