As you can see it’s located right next to the GPIO pins and a chip marked as 4F. What I can see on it is first two letters of the marking are TT. But can be different on yours.
Hello again. So I finally got back to checking the schematics and found out that files you shared are for the board P3449, but I need schematics for P3766 - I have Jetson Orin Nano, not just Jetson Nano - my carrier board has USB-C port and not micro USB and many other differences, so I was unable to find the needed component on that schematic.
Please share the right files if possible or better yet just tell me what that component is.
hello, do you have the back of P3766 Orin nano carrier board design files, I downloaded but found above is P3768, I lossed some component there, there is no c157 on my board, and u55 seems burned. @sgursal@in_sympathy
Hi. U55 is AP22811AW5-7. It was getting kinda hot on mine as well - 46° C on idle with nothing even connected to USB-C, so no surprise it got blown.
As for the cap - here it is on the schematics, but it’s crossed - in my understanding it should not be there anymore, so if that’s the case - you didn’t loose it - it was never there, so don’t worry about it. Pads for it look factory clean on your attached photo, so I guess leave it as is and just replace the chip. On my board there was no C157 either.
Thank you very much. I previously thought that the absence of C157 at that location had caused U55 to burn out, but it turns out that C157 wasn’t supposed to be there in the first place, and I had been looking for this model all along. I noticed that U55 was smoking when I turned on the device, so I quickly unplugged the power, but it still burned out. I’ll buy an AP22811AW5-7 online and try replacing it.
I’d also recommend checking for a short around the P-channel mosfet that got blown on mine - check above - since those may or may not be related. Or for any other shorts around USB-C - you may replace the chip and something else may cause it to blow up again.
thanks a lot for your suggestion! I almost forget to check it my own. I should be careful and check if there is a short around before I put on a new one, I guess there is a short capacitor, much appreciated. :)
