Long story short:
>Working on a team project
>guy hands me some leftover components to let me work at home
>among these, a 20x4 lcd with a i2c driver
>testing the display back at home
>backlight works, contrast trimmer doesn't work, doesn't even shows the rows indicating a missing i2c connection
>check the GND and VCC pins
>see this
What kind of damage is this, is it because of soldering or was it fed a higher voltage than 5V?
