If it's not what you're looking for, why did you mark it as the solution?
To unmark it, see here.
You can't expect there to be an off-the-shelf design for every possible application just waiting for you; at some point you are going to have to do some actual design work yourself - or pay someone to do it specifically for you...
Why do you particularly want to do this on an STM32F407VET6?
PS:
If you do want an off-the-shelf design, then just go by the performance/feature requirements you need - rather than the processor it runs on.
Sounds like a Raspberry Pi would do ...
A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
