I received a 3DS console today that had been cracked in half at the hinge. As I opened it up to remove the motherboard I immediately noticed that the tiny little IR board that normally connects to a plug next to the P7 connector was missing. The IR module on this motherboard was integrated and not removable. Also strange was the fact that the little piece of tape used at the factory to secure the touch screen connector was black, rather than the typical white. I’ve seen a few boards with black tape rather than white, but in the past I always assumed this was because they had already been worked on before I received them and the last technician had used black tape. Now I know I was probably wrong. This was an entirely new motherboard revision.
In any case, this board does look more or less the same as any other model besides the fact that it has integrated IR and some silver screws in a few locations that normally have black screws. The color of the screws does differ from model to model, but I’ve never seen silver screws in these locations before. It’s fairly common for the external screws for the housing to be silver on special edition or bundled consoles, but I’ve never seen anything other than black for the screws beneath the SD card slot. Additionally, some special edition and bundled consoles have only two, rather than three, screws securing the L button in place and only three, rather than four, screws for the R button. This console follows that pattern but it also replaces the normal black screws for the shoulder buttons with silver ones.
Unfortunately, the previous owner used super glue in a misguided attempt to repair the cracked housing and even glued the battery cover in place, leaving no possibility of salvaging it. But the serial number sticker inside was still legible:
For now I’m keeping this board. I put it inside one of my own consoles and sold the motherboard it replaced. I’ll probably keep it around for a while to tinker with and maybe I’ll eventually sell it.
You updated! I love your posts about Nintendo 3ds innards. This one’s just as interesting.
Are the ctr-CPU-20s and the ctr-CPU-01s interchangeable? I’m replacing the board on the former, but I can’t find any for sale.
Yup, they’re all 100% interchangeable.
