Your project mentions several VDD (Positive Power Supply) and VSS (Ground) terminals which are typically used for connecting power in a circuit. In absence of a power source component in the provided information, I'll suggest a generic way to connect power to this STM32 microcontroller.
Connect VDD terminals to the positive rail of your power source. The terminals are - VDD (Schematic Position: 21, 856), VDD (Schematic Position: -21, 856), VDD (Schematic Position: 0, 856).
Connect VSS and VSSA terminals to the ground rail of your power source. These terminals are - VSS (Schematic Position: 0, -856), VSSA (Schematic Position: 21, -856), VSS (Schematic Position: -43, -856), VSS (Schematic Position: -21, -856).
The VBAT terminal (Schematic Position: -43, 856) is typically connected to a battery or a secondary power source.
Please make sure to validate these suggestions against the STM32F103C8T6 datasheet and your project requirements.
