ELECTRONICS / PCB

Turning system requirements into a board means separating power, sensing, processing and actuation clearly enough that the hardware can be routed, fabricated, assembled and debugged.

LAYOUT / MANUFACTURING

From logical blocks to physical constraints.

Power paths, sensitive signals, connectors, protection components and mechanical clearances all become physical decisions during PCB layout. The deliverable is not the KiCad canvas — it is a board that can actually be fabricated and integrated.

REALITY CHECK

The board is only useful when the machine accepts it.

Connectors, wiring, serviceability, power handling and debugging matter just as much as the schematic. The electronics case closes only when the physical system can use it reliably.
