¿Por qué estás usando 4700?
(4,7k ohmios)?

Necesitas una resistencia de 470 ohm

Editar: pueden ser de 470 ohmios, mídalos para asegurarse

they are 470 ohms

You need 47 ohm (label in"470 " or "47R0") resistors, not 470 ohm. Stop making confusion like WS rp2040-tiny rev1.0 using 470ohm built-in wrong resistors.

either you stack 4x 470 ohm to make it around 100 ohm or just replace them with proper resistor.

srry i meant 47 ohm not 470*

What kinda math are you doing here buddy?

4 x 470 ohm is still WAY too high.

I think your meaning is to say, they need four pieces of fourty-seven ohm resistors in total. They can then solder two fourty-seven ohm resistors together to make ninety-four ohms, or one-hundred as many people will just round up. Place two of these "one-hundred" setups on the CMD and DAT0 lines, in order to result in a total of 94 ohms on CMD, 94 ohms on Dat0, and 47 ohms on CLK.

4 x 470 ohm is still WAY too high.

4 of 470 ohm sandwich together(parallel) equals to 470/4= 118 ohm. It would be high but not much compared to 470 ohm.

By math, 10 of 470 parallel would come to 47 but kind of too much waste.

Why do you keep saying 470 ohm? They are not. They are 470 or 47R0 SMD labeled, for 47 ohms.

I guess you're bringing resistor theory into this, by paralleling resistive values, but that makes no sense in this context, as that would just be adding extra thickness to the pico that we are already trying to get rid of.

cz @Trivisuko the guy who post picture using 470 ohm wrong resistor in his setup. 470 ohm is WRONG FOR SURE.

I wonder if he ordered more than 3 470 ohm from seller, so that he might have a chance parallel the wrong resistors in order to make the setup semi-success before ordering 47 ohm

Sadly, if they had just RTFDG, they would have seen the photos of the resistors that are labeled as 47R0, and they could have avoided all this, but I get the feeling there are a lot of people not reading the guide.

i mean its been explained more then enough in the threads though that should be enough, plus ur guid hase been downloaded quite often so i would guess the people would also read that so i mean i dont understand it eather Xd

very true, just like what rp2040-tiny initial came out in fast pace, 470 ohm on the board making whole batches goes off the shelf.

FYI, this thread is so hot that less people willing to spend time reading few pages or even using search tool finding those well spoken answers.

Why are u using 4700
(470k ohm)?

U need 47 Ohm resistor

Guys, thank you very much for everything, I don't know what happened to the resistors, what a mistake, it's already working 100%.
1000 thanks

I have a question about the Flexcables of the modchips.
One is 1v1-7 and one is 1v1-6.
Is there any difference or can i just use a modchip shipped with a 1v1-6 cable with a 1v1-7 Flexcable?

how should we know what

1v1-7 and one is 1v1-

is?

u want us to search it for u to give u a answer ?

uploads pics from it and u might get a faster answer

I knew they were 47 ohm resistors, but I have a resistor book and for some reason I put the 470 ohm resistors, it was my mistake, the tutorial is perfect

 

[Bozohaha]

sorry

awesome, now we know when DAT0 CLK CMD resistance too much , we may have error code =***

should be no difference for v1 erista console

if u look at them where they solder together they have the solder pads on the correct space so u can use both...

They're both for V1 switch but to me the one on the left with -6 looks like it's higher quality. Larger pads with cleaner edges. I would use that one F1V1-6
