hello guys, I think I might be asking a very basic question but by seeing the SMD Ic which I have got are having a dual notch and I am a bit confused with choosing it.
can someone suggest to me the proper side of the notch?
and which pin is to be considered as the 1 or Start?
presently I am using STM32L412R8T6.
Thanks in advance.

Does corner (4) have a chamfer, and the other corners don’t, or is that just the photo?
If so, I’d go for pin1 = chamfered corner.

hi,
Also, if the dimensioned sketch is used as a guide, the location of the 'indented dot' at #1, lines up exactly,
