Arduino leonardo burned?

Development Tools IDE 1.x

Good afternoon, I hope you can help me with my problem.

It turns out that about 4 months ago I started my first semester of electronics, I had to do a project so I bought an Arduino Leonardo. One day I got to connect an external source but I forgot to check that the arduino supported it, I connected a source from 19v to 3.5amp obviously the second burst the voltage regulator "ams1117". As I had almost no knowledge of electronics, I decided to buy another Arduino to complete my work. Now I wonder, is there a possibility to save that arduino? either by changing the voltage regulator, or is it already burned something else?

Thank you in advance for your help.

By the way, does anyone know what the component that is in the red rectangle is called?

I think that's the opamp used to do power switching and buffer pin 13 for the led. Abusing the power rails usually kills that - fails to near-short.

But with a 32u4, you probably trashed the MCU too. The usb AVRs usually die when you abuse the power rails. Unless you value your time well below minimum wage, it's probably not worth it to try to fix it
