From the project

Embedded power regulation PCB with telemetry, health monitoring, and fault detection for CubeSat electrical power systems.

The CubeSat Power Management System (CPMS) is a custom electrical power subsystem (EPS) development board inspired by CubeSat power architectures. Its purpose is to design, manufacture, and validate a professional-grade power-regulation and health-monitoring PCB using an engineering process representative of aerospace hardware development.

Unlike PCB projects focused only on schematic capture and layout, CPMS covers the complete engineering lifecycle: requirements definition, system architecture, component selection, design analysis, verification planning, hardware bring-up, firmware…
