i tried but for the life of me the solder wouldnt stick to the copper pads, it was impossible lol

and yeah i mean the top 2

What copper pads? For instance, I soldered my RP2040's ground to the body of the USB-C connector.

After doing a flex install, admittedly the mosfets can be easier if you are good at manipulating things with tweezers.
The flex can be easier, but you have to install it a very particular way with pre-tinning the solder pads on it,

I find it easier to not pre-tin any of the flex cables

oh, i was thinking of using the screw hole circles or the arrow next to the dat 0 pinout, but doesnt distance matter here? wouldnt the usb c connection port be too far and cause issues?

also is there a way to test if my switch is stable after the instalation? is there a way to check out that i did everything successfully?

Which point are you soldering to ground? If you are soldering the RP2040 board to ground (for power) then any ground will do, just try to use thicker wire (around 32awg or 30awg) for the 3.3v and the GND.
If you are doing the ground for the mosfets coming from the Source pin of the mosfet, then yes, ideally you should have a short path to ground.

Here is how I did my switch lite earlier today. I posted this in the main Picofly thread.

no worries for the length of gnd point, just use a good wire.

this is where i was trying to get ground from, the screw hole coper circle and the arrow beside it. But if the usb c connector works fine ima use that from now on lol. thanks!

Are you using flux??? Because if you aren't using flux, start using flux.

im using official amtech flux, lol i swear i was cofused too on why it wouldnt stick.

hey, the chip is showing up green, as if it was succesful but now its just jumping me into ofw. it was working just fine before

 

[ngoanrazor]

Can somebody help me, i‘ve broken the pads for clk and somehow even lost the resistor? next to it. Is there an alternative point so i can fix my switch and what is the value of this resistor/diode?

You can solder it, it have VIA point under pad

Where is the digram v1 arista that the 3v3 point smd capacitor near togther... Or there 3v3 in there another point????

Check the definitive guide, or use the point on the EMMC that was shown to you in the other thread.

Anyone know the value of this caps in red? its a V2 board. I broke it when try to lift the header, leason learned. Also Is there any replacement in the rp board?

 

[IBBYEdwan93]

Hi All, do we have a diagram for the lites alternate soldering points?

Those are capacitors that are the same as the ones being soldered to on the APU, that can be robbed off the RP2040-Zero (see the definitive guide). They are 100nF 0201 capacitors.

Fun fact, those two capacitors affect whether or not your console has bluetooth and wifi capability (ask me how I know)

ive just finished soldering all the point and final test before connecting to pico i tried to turn on the console to ofw, but everytime i put on the soc cover the switch wont boot only blank screen i can feel the soc heating up

when i lift the soc cover the switch turned on normally to ofw, does anyone have an idea what happened? where to find the short?

tried to isolate everything using kapton tape does nothing

Check below the flex (1)
Remove some solder from the caps (2) if possible.
Check the soldering on this capacitor (maybe just bad photo)
Clean everything around APU with IPA just to be sure
It looks like one string of multicore wire is loose and might be touching the ground on cap (3)
Again, it's difficult to troubleshoot using a photo...

In the v1 if you soldring cmd dat0 rst 3v3 clk on nand mmc.. Is that damge chip on v1 or no???

If you are careful, you will not damage anything.
It is ok to solder to nand board.
Or you can combine both, solder some on Nand and some on alternative, whatever works best for you

So far i only read from the thread the 3.3v alternate.

Here is interesting site if you want to search it yourself.

you sir are amazing. this tool is incredible !!

with this has anyone tried going for alternative points to the cpu resistors?
