I put a screw in one of the holes of the pcb of the NodeMCU and I damaged it (removed a component ).
And I cut one of it 's pins, so I can 't resolder it.
I think it 's a diode, it's connected to the output of the ASM1117.
Marked with the red arrow pointing to it on the picture.


What is it?
And what can I replace it with?

EDIT: I just noticed it 's marked with letters 'S4' on it, so it must be a diode, 1N5819 SMD Schottky.
If someone can confirm this, I 'd appreciate it.

Some schematics show an ordinary diode but a schottky is better here. 1N5819 should be fine.

Thanks!
