Hello,everyone
I have questions. Why there were two different types of chips?

Which one is original?

From the ones I have built #2 looks just like them, it is not rare they make small revisions to layouts or components.

both are original if you bought them from an authorized evolv retailer or evolv themselves. looks like they switched manufacturers regarding the inductors. just like when the screen shortage happened. they had to source another screen manufacturer to keep up with production.
