Mechanics use silicone grease to discourage corrosion in cars, has anyone used some dielectric (silicone) on a DAT0 adapter for long term testing?

Not that I would ever use a DAT0 adapter but just a question

Installing the chip on the V2 is like childs play level as far as soldering goes, super simple to do.

Couldn't even agree more. Opening the device takes even longer lol

Could you explain what would be your idea? I use DAT0 adapters!

A dielectric would prevent a good contact. Maybe something like DeoxIt then? Haven't tried, I prefer a reliable solder joint.

any idea what the issue is when i get long long short yellow light?

why the h3// i cant boot into CFW anymore? tried vol- + power to bypass into Hekate but nothing happen. the LED just blinks green and then red into OFW wth!!

Hello to you all people here.I have two questions
First.Can somebody tell what the two pins i have circled in red on RP2040 are used for.I think the one is the cpu right?But the last one.I have seen it being soldered in installations but i dont know its purpose

Second,I have this chip.Can i used it on a nintendo swicth?

Thanks

Unce upon a time there was this guy @lightninjay who made an awesome guide on how to do this:

A definitive PicoFly install guide

This is to help install the PicoFly hardware mod on any and all Nintendo Switches

Hello

Looking to use the Rp2040 3-in-1 kit on a switch lite but was sent the flex cable that had the incorrect pinout. Any place to buy the correct power/flex cable with the correct pinout?

Can anyone tell me what’s going on it was working before then it just stopped working

Hi, does anyone have any details of how much can be removed from an RP2040 Tiny without losing functionality?

I'm talking in terms of components and trimming the PCB to be as small as possible.

I'm installing one into a custom OLED Switch with a transparent case and I'm hoping to reduce the size of the chip as much as possible.

I'm sure I've seen a picture somewhere but can't seem to find it.

I think I've seen a solution somewhere in the other Picofly thread, of someone mounting the entire picofly on the reverse of the main PCB, so it is effectively sandwiched under the Motherboard and attached to alternate points that minimize visibility.

Sorry I don't have a direct link to the post at the moment, but maybe this will help you in the direction of hiding the chip in a clear case.
