Board Farms for Everyone: Making Hardware Debugging Easier and Sharing Boards...
summary
Build of a cheap home board farm proves interactive hardware debugging is practical: a Raspberry Pi runs LabGrid controller+exporter on Raspberry Pi managing four DUTs (goal ~10) with consoles over USB, power cycled by Sonoff Wi‑Fi relays with ESPHome MQTT (about $6–7 each), images served by TFTP and tests triggered from GitLab CI. It works for live console, flashing, and locking, but faces USB‑hub reliability and manual SD/image copy pain points and needs arm64 containers and GPIO drivers.
