Power Source Selector Module #Module
This project is focused on developing a versatile power source selection system capable of intelligently managing multiple power inputs including battery (VBAT), solar (VSOLAR), USB (VUSB), and VIN. The module is designed to ensure safe, efficient switching and regulation between these sources while integrating key protection features and diagnostic indicators. It lays the groundwork for further integration with broader systems, ensuring that power delivery is both reliable and adaptable to varying load conditions.

- A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
