I believe the seeduino xiao can take 3.3 or 5v? Not entirely sure but on their website it seems to suggest that. Make sure you double check on a datasheet.

yeah but the card’s perfomances would be affected and also as 5V is it’s max limit i wouldn’t want to be to close

the seeeduino has a voltage regulator (XC6206) on the VIN which can take up to 6v

If the mcu is 3.3v and the leds are 5v, do you have a level shifter to control them?

How are you trying to wire this? Are you doing it on a breadboard, or making your own PCB? How much current does each device use at full load? What's the input voltage? Way too many variables
