Design Notes

Decouple each VDD pin with a 100nF ceramic capacitor placed as close as possible to the pin. Additionally, add a 4.7uF bulk capacitor on the main power rail. For the VDDA pin, use a 1uF capacitor and connect it to VDD through a ferrite bead to reduce noise on the analog supply.

Ensure a solid ground plane under the MCU to minimize noise and improve EMC. Keep high-speed signals (SPI, USART) away from the crystal oscillator pins (PF0/PF1) to avoid interference. Use series resistors on clock lines to reduce ringing.

Do not leave unused GPIO pins floating; configure them as outputs or enable internal pull-ups/pull-downs to avoid excessive current consumption. Also, ensure the BOOT0 pin is properly pulled low for normal boot from flash, and verify the NRST pin has a 100nF capacitor to ground for reliable reset.
