It's yellow now with the last pico fw

I found this on ali, its a new model ?
@QuiTim

Looks good. They are also selling this "New" model now and it looks good on photo.
But as we already discussed it here, if anyone plans on doing more installations in the future it would be good to start doing reball/reflow of emmc since I think it's safer in the long run

Now the real question is is do you know if there’s one on another switch board I can pull from? I don’t have any spare oled so it would have to be a v1, v2, or lite.

Yeah there are like at least 2 I know of on the v2/V1 boards on the right wider of the emmc connector and and at least under the WiFi chip, get ur multimeter out and take some measurement on these 2 points

Doing gods work. I really need to recompile the latest information and troubleshooting

Hahaha no not doing gods works Xd

Just helping the folks out ;-)

Thank you!

Thank you!

No problem

I meant *on the right side of the emmc connector Xd

Here discussed in the other thread should be also 4,7k

So I grabbed the circled component and put it on my oled and now I’m getting the ==* error code I wasn’t getting that error before.

 

[sogun26]

Does anyone know the value of this little guy for CMD on an oled? Accidentally took the end cap off.

10k 0201 smd

 

[jkyoho]

10k 0201 smd

Are you sure?

What are u talking about its 4.7k

==* is CPU cable if I remember correct don't have the list on hand so something wring with ur CPU line /mosfett install

 

[sogun26]

Are you sure?

yes im using 10k 0201 rersistor for replace my oled

 

[abal1000x]

yes im using 10k 0201 rersistor for replace my oled

You should state it something like:
'I replace it using 10k 0201, and its working normal'

Your sentence make misinformation as if originally its use 10k which is not.
As far as i know, that pull up resistor for all nintendo switch use is 4.7k.

Early on when switch oled board came out there were people who replaced that resistor with 10k and it worked fine, you also have 1 or 2 youtube videos of people using 10k. But the fact is that the correct value is 4.7k so it seems there is quite a wide range of resistance that works there.

well said
i would use the original value cause there is some reason they chose that one :-)

Yups, i recommend the same.
If possible, use the same value 4.7k.

We don't know about the datasheet on Nvidia tegra which is this cmd line goes into.

 

[Dee87]

From the datasheet:
View attachment 379613

okay so u can use to 100kohm yes?

but still the lower u can go the better it is i would say.
if i remember correct the higher u go ,the higher the issue is that there are chances of the "bus floating" in this case.

im not a engenier im all self taught so my answer about the floating could be wrong so dont take my word on that

According to emmc datasheet, yes, you could use 100kOhm.
But we don't know the characteristics of the nvidia tegra which that cmd line goes into, since there is no datasheet from the manufacturer.

I am not too sure on what resistance is the best whether using low or high. I don't have sophisticated oscilloscope to see the differences. I once work on quartz crystal manufacturer, each one of the measurement device for creating datasheet comes from agilent, which the price is like 10-50 times of brand new iphone . Still looking in 2nd market for cheap one

Theoretically, higher resistance, lower current, higher noise, bad signaling. Lower resistance, higher current, lower noise, good signaling. I think that is why nintendo choose the most lower resistance the datasheet allowed.

yeah thats what i still remember :-)

First of all who in the hell would even want an IPhone Xd

yeas oscilloscope are pretty expensive specially if u want a really good one, but there are also some very good cheap ones on the market
