STM32 board simplification suggestions

Nice work Stephan.
SOT-23 regulators like the XC6206 are a bit cheaper, and an easier form factor for soldering.
I'd consider a single 1uf capacitor on the input and output. Mixing 100n, 1u, and 10u adds complexity to the board and can cause resonance problems.

I also think 1k would be fine for the reset pullup, which would mean all 4 resistors could be the same and allow use of a 4x1k resistor array. I suspect you could design the footprint to support a single 4x1k array or 1 individual 1k resistors.

Thank you for the tips and the link to the article. I think I've already used the XC6206 in another one of my projects. But I don't remember why I used a different one here. When I find some time again, I'll implement your suggestions.
