STM32F405RGT6 custom board review

[ekremtrn]

Hello everyone, this is my first post on the forum. I'm starting to learn STM and have created a custom board using the STM32F405RGT6. This is the first board I've created, and I wanted to check for any errors before sending it to production. So I've uploaded a PDF of the connection diagram. I'd be very grateful if you could review it and let me know if there are any mistakes.

Do you have experience with any other microcontroller(s) ?

Before leaping into a custom hardware design, I would strongly recommend that you prototype & gain experience on a development board - far cheaper & easier to find & fix issues than on a custom design!

Did you study Application note AN5093, Getting started with STM32G4 Series hardware development boards?

I don't see any programming/debug connector ?

Have you considered how you will debug & test your design ?

See Design For Debug ...

PS:

It would also help to give details on the intended application of this board, and what environment it will operate in - these will affect the design
