Short question regarding the contact drillings

[timbo2023]

Good Morning Ladies and Gentlemen,

 

Could you communicate in a short way the size of the contact drill-holes (stm32f411 - CEU) ?

The diameter in AWG size would be enough.

We also are interested in further documentation-links regarding it.

What is "contact drills"?

Are you talking about some of the development boards, e.g. Nucleo?

Hello @timbo2023 ,

Not sure I understood the question.

Could you please elaborate more or show image(s) or something similar to explain what you're talking about?

[timbo2023]

How many kind of holes to you see on a stm32f411ceu controller card?

Which diameter has this hole in "AWG-size"?

ST doesn't make that board, you'd need to ask the manufacturer.

 

But header pins plated through holes are typically around 1mm or 40mil, which is 18 AWG.
