user53592: I know that this topic does not apply to Arduino, but for me it is important to find a solution to the problem. I know the consequences.
I'm creating a pcb board into which the original ESP32-DevKitC-32U module will be inserted. I can not find the original dimensions of the board, in particular the distance between the contact rails. The site espressif has a small description.

27.9mm is indicated here. It is not clear to me, is this the full width of the board or the distance between the contacts?
What I want to do:


It is very important for me to find out the correct dimensions of the original board. Maybe someone has such a board and can measure this size?

user37622: The distance of the headers is breadboard and perfboard compatible for 0.1" (2.54 mm) pin standard. 25.4 mm is 10 rows.
