    Hello DYann.1,

    please check-out the user manual for this board available here. 3.3V Power supply outputs are available on the following position: CN5 pin 38, CN8 pin 38, or CN9 pin 38. The pins should also be marked with 3V3 label.

    Here's a schematic, might want to be careful about how much current you draw, and perhaps have your own supply/regulator, and use a common ground

    Fix the search, then it might find things..
