Hopefully it’s not too hard to see in the pictures but there are pins “missing” in one OEM charger compared to another. Does anybody know why this might be? The reason I’m wondering is because the charger with the “full” set of pins is continuously frying the M9 ic on a particular switch I have whil…

[image] Switch charger missing pins? Nintendo Questions Ah, didn’t notice that to begin with but on closer inspection, it seems theyr’e manufactured by differen’t companies, one is made by Delta and you can see a basic pinout printed on the case, the other is made by Zebra…

I wonder if this explains why some switch boards have those added 7C diodes? The switches that ship with the lower quality charger have the added circuitry? Also just to clarify, you’re saying the charger with less pins is produced by Delta and is the higher quality charger?

[image] OhItsSlick: I wonder if this explains why some switch boards have those added 7C diodes? Interesting idea and a possibility but I think the removal of these diodes (and others elewhere on the board) was just a cost cutting exercise, they are on a lot of the early rev boards. Strong in…

Yeah going by the marking on both of my chargers, they’re both made by Delta. I guess I just need to charge this switch with the charger that has less pins. Thanks for the discussion!

Sorry I missed the part about one of the revisions/variants causing your M92 IC to fry, there is very likely a reasonable explanations to this, the first being that one of the AC adapaters is just faulty the other is that perhaps some of the pins (which we assumed were NC on one revision ) which cor…

Good idea. Here’s a picture of the base. [image] I also just plugged in a breakout board to the switch motherboard and found there was continuity between VCONN and CC. I presume this is a bridge?

I noticed the difference in charges too, I put it down to them getting rid of the pins they don’t need, just incase they bridge and damage the internals on the Nintendo switch
