P-Nucleo-wb55 VDD Pins?

Hi all,

Coming from Nordic nRF52840, I have a project that uses a Joystick.
I bought two Nucleo boards, the P-NUCLEO-WB55 and the NUCLEO-WL55JC1 to test Radio communications.

My Joystick of course uses 2 channels (X and Y), uses 2 GND pins, but also uses 2 pins for 3.3V (VDD).

Now after checking the official Nucleo manuals, I can find only one 3.3V  VDD pin.

Is that right? Those development boards offer only one 3.3V pin?

If yes, what are my options?
Power the joystick with that unique 3.3V VDD pin? Just like it's done on most small boards (like the blue pin)?

Thanks for any light and help you can provide.

Ok,
Well i didn't do it myself before, it was handed to me this way.
But I'm glad to read I can split. I was just unsure whether it was drawing too much power and wouldn't work.
If you mention even 5 wires, I guess I'm good to go.
Thanks. That's clarifying everything. And I won't start searching for a board with more VDD pins if one is enough.
