Request for review of power connection schematic for stm32f051r8t6

Dear team, hello, I've drawn a power supply circuit diagram for the STM32F051R8T6 but I'm a little hesitant. The diagram of my circuit is below. Have I done it correctly? Thank you for your answer.

BOOT0 should be tied or pulled to ground.

You need some way to program it. An SWD connection on a standard programming header like STLINK-V3MINIE or similar is recommended.

Otherwise, looks good.

Power nets and decoupling capacitors could be drawn a bit cleaner.

 

Follow the design guide:

For lower ADC noise levels, place a ferrite of approx 1k ohms at clock frequency between 3.3V and VDDA.
