Circuit Principle:

Power Supply: VDD is the main power input for the microcontroller (2.7V to 3.6V). VSS is the ground pin. Reset Function: NRST: This pin is used for external reset functionality, where pulling it low resets the MCU. Serial Debugging: SWDIO and SWCLK are used for the Serial Wire Debug interface , which allows debugging and programming of the microcontroller. Analog Inputs: Several pins, such as PA0 to PA15, PC0 to PC5, are analog-to-digital converter (ADC) inputs. These pins allow the microcontroller to read analog signals, such as temperature, light, or voltage. Digital I/O: Most pins function as GPIO (General Purpose Input/Output), meaning they can be configured as input or output for controlling and receiving digital signals. Communication Interfaces: UART, SPI, I2C, CAN, and I2S interfaces are supported by various pins, enabling serial communication for interfacing with other devices.
