... Thanks for all the great people involved in making this Mod possible!

I see no flux *angry noises*

Sure you can solder all pads separately. But as I see, you use a different, much larger mosfet, I'm pretty sure single one is enough, no need to setup dual

IRFHS8342 MOSFET is used...

why dont u take the images out of the aio thread

This wiring is very smart but difficult.

Guys, I'm having cyan led and starting directly original system? ideas? I already soldered 2 mosfets, it only worked with the flat v2, but I wanted to know the reason for not working with the mosfet in this lite, I already made other devices that worked ok

..this is only what i got on hand..

I mean show photos of the board, since it's hard to see where exactly those wires are soldered to. My diagrams assume soldering directly to the eMMC board, or, at least, to its header, I am unaware of other points. Just wanted to check

In the same message you just quoted

Thx for the quick reply, mate!
I mean where are all the firmwares being posted? Like a repository?

Also, what does sufix "_I" mean?

Does anyone know if Sx Lite flat CPU cable would work with PicoFly? I have that one installed and I would like to replace SX with PicoFly. My SX is really unstable.

your wire looks too thin, remember, it should handle around 20-40A in pulse

find 0.2mm diameter wire, properly solder it to the mosfet

why not, it's the same cable, should work same way

no repository, I delete older firmwares and add the latest one in my post. however there is an unofficial one on github.

I described the difference a few posts earlier, _l means longer timeout

I fitted a SX Lite CPU cable in mine, it worked fine. I mostly ordered as it had a faster delivery time and I'm super impatient

seu fio parece muito fino, lembre-se, ele deve lidar com cerca de 20-40A em pulso

encontre fio de 0,2 mm de diâmetro, solde-o adequadamente ao mosfet

por que não, é o mesmo cabo, deve funcionar da mesma maneira

sem repositório, excluo firmwares mais antigos e adiciono o mais recente no meu post. no entanto, há um não oficial no github.

Eu descrevi a diferença alguns posts antes, _l significa tempo limite mais longo

I've done other installations with this wire, it worked without problems, but I'll try another one next time

 

[rehius]

is there any donation link for you?

no

From the photo it also looks like cold joint for the S wire

no

Yeah, I solved it the best way (I put the flex of v2 in that lite) but now I got a v2 and soldered the mosfet directly to the capacitors, even though it was a v2 nand toshiba it worked super well with fw 2.65. Thanks for all my friend!

Where can I download the latest firmware

Check "Important Posts" tab at the top of the page for a link called "Firmwares"

Best of luck, mate!

If you find it too difficult with the thick solder wire, try getting something like 0.25. I find it much easier to work with (less bridging etc).

And if you find it too difficult with the 0.2mm magnet wire, then going to 0.1mm might make it easier still. Although on lite it might be just fine.

And lastly, if the liquid flux burns off too quickly, then “kingbo rma 218” tacky flux from AliEx is decent. Not amtech, but decent.

I encountered an issue while using the 2.5 firmware. The rp2040 lights up in blue when turned on, but after pressing the reset button of rp2042 after turning on, the rp2040 lights up in blue for 5 to 15 seconds before entering the atmospheric guidance interface.

Please see my earlier post about getting the LATEST firmware. The tab at the top should redirect you to a post by Rehius with the 2.65 firmware.

It said that my old switch was stuck in the boot interface after I pressed the reset button of rp2040 (the green light of rp2040) during boot. I pressed the power button of switch for a long time to enter the boot logo again, but the switch did not enter the system but entered a screen. In the middle of the screen was a horizontal line like a progress bar. Above the horizontal line was a large square consisting of eight small squares. I waited for a while in this screen before the switch automatically turned off, and then entered the previous screen on the startup logo. After waiting for a period of time, the switch automatically turned off and can no longer be turned on.

why difficult ?
