Basic Example:

To power the microcontroller and set it up for basic operation:

Power Connections:
- Connect VDD (Pins 24, 36, 48) to a 3.3V power supply.
- Connect VSS (Pins 23, 35, 47) to ground.
- Connect VDDA (Pin 9) to 3.3V $\text{(for analog operations if needed)}$ .
- Connect VSSA (Pin 8) to ground.
- Optionally, connect VBAT (Pin 1) to a battery for backup power.
Reset and Boot:
- Connect NRST (Pin 7) to a pull-up resistor to 3.3V and a switch to ground for manual reset.
- Connect BOOT0 (Pin 44) to ground for normal booting from flash memory.
