Main things about this photo is that some of the board is cut off and there's a lot of dead space at the top, so definitely centre and align the object.
The angle also feels a bit off, perhaps try a longer focal length so the perspective is less accentuated, or dead centre over the top so it's more even. Although if it's for assembly instructions, it might help to take the photo from where someone might normally be looking at the board from. (Sorry if I'm being too critical)
