Setting 3.3V on STEVAL-USBI2CFT Adapter

Hello,

I'm trying to set the voltage to 3.3V on my STEVAL-USBI2CFT adapter, but I'm unclear on how to do this. The user manual (UM3226) mentions setting the voltage via soldering jumper JP4. However, my board has seven solid pads labeled J8, J4, J5, J6, J7, J2, and J3, which don't correspond to the documentation.

Could you please advise how to properly set the 3.3V output using these pads?

Thanks in advance for your help!

    -> seems obvious, which solder bridge -> for 3v3 .

    Thank you very much for your quick response. I don't know why I focused on J-pads and didn't notice this myself.

    It is somewhat very technical.
