A credible budget phone farm is hardware-first — not a pile of random USB hubs.
Budget stack (reference) - Exynos N5 entry 20-node chassis from $428 USD (hardware tier reference) - Express shipping varies by country — see /shipping for estimates - Optional: used compatible Android devices sourced locally vs factory-configured modules
What not to skip - Active cooling — passive desk setups fail under load - Labeled USB paths — saves hours when one slot drops offline - Burn-in before production workloads
Realistic expectations Budget tiers handle lighter automation and pilot QA. Plan upgrade to S8+ or S9+ clusters when scripts, video, or storage demands grow.
