Hi! I am looking for a replacement for a SP2 board (I’ll leave a photo attached) and I would like to know if this model of board would be compatible. From what I see they are quite similar (except for U5), but I would like to confirm before making the purchase.

Thank you very much!

Take a look at D7 it looks like heat has displaced it. I couldn’t see the u5 legend and so couldn’t tell anything about you question. I would look up the schematic and do some voltage and signal checks before paying the $400-$600 with shipping for the main board.
