This listing is a spare/replacement A1466 820-3437 logic board family offering Intel Core i5 CPU variants (1.3–1.7GHz) and LPDDR3 RAM configurations (4GB/8GB) plus high-density PCB construction. It’s suitable as a direct repair/board-swap part for mid‑2013–2015 MacBook Airs, but expect repairer-level work: reviewers note SMC/3.3V rail troubleshooting, possible prior rework/liquid damage, and occasional need for SMC reflow/reball.
Techs or experienced repairers needing a compatible A1466 logic board; avoid if you lack soldering/reballing skills.
