When Mara joined the engineering team at Lumina Controls, she inherited a dusty project: a compact motor driver that needed reliable isolation between its noisy power stage and the logic controller. The board had to survive electrical transients and meet safety requirements, but the tight budget and small PCB area meant they couldn’t use bulky transformers or expensive digital isolators.
