What you'll build
Some measurements demand galvanic isolation — a complete electrical break between two halves of a circuit, for safety and noise immunity. You'll bridge SPI across a digital isolator and power the far side with an isolated DC-DC converter. The catch you'll solve: those converters are noisy, so the isolated rail has to be cleaned up before it can feed sensitive analog circuitry. Essential prep for the EEG front-end.
It sits on the COMMS track: wireless links and meshes that get boards talking to each other and to a hub.
The build pipeline
No steps skipped, no black boxes. Each stage is gated on real proof of work: a clean ERC, valid gerbers, a passing bring-up. You finish having actually done the engineering, not just watched it.
