With little experience with electronics and comming from an Arduino background I am designing my first STM32 PCB.
My question here is, since this is my first attempt, I would like to have some advice to check whether is anything wrong with this design? Are there any obvious flaws with it?.
- I want to make us of the ADC , are the ferrite beads placed correctly, should I use only one?
- Should I place more decoupling capacitors? I have seen designs with more of them and others with less.
- Why is the resistor between the resonator (R10) used for? Not all designs seem to include it.
I'd also be glad to hear general opinions about the design.
PS : It's a minimal design working on batteries, I have not included the regulator portion and other parts of the circuit as it's not relevant to the question.
