Kess V2 Harware Rework - FREE SOLUTION!

you have to solder all middles to gnd
so run a wire across all centres then from last 1 to any gnd point
and for the holes yes just solder them

Thank you very much tango for helping.
So basically like in the picture? (yeah its ms paint)

Or I am messing up grounds and should look for any GND on the PCB?

Hi g00re,

I don't think you want to solder a wire in the murata filters!

He said that you need to solder the middle holes, they are located in the middle of the PCB.
This is the original board (picture taken from the first post):

As you can see, in the middle of the PCB the holes are filled with solder.

[tango]

you have the idea right apart from dont connect them to any end of the filters otherwise thats then a short circuit

[ankjay]

tango,

Sorry my n00bice but, is it necessary to solder a wire on the murata filters? :-|

[tango]

you need to make it something like this (making sure the centers are not connecting to outer ends anyway

[tango]

if your pcb is the 1 with no trace for them in centers yes its needed they are connected to gnd

I'm waiting for my to arrive... It's the one from Bokins store, it should look like this:

From what I see, they are connected, right? It's only necessary filling with solder the holes in the middle of the PCB. From what I see.

[tango]

you dont have to fill holes
all you need to do with that pcb is check transistors are good etc
no need for filters replacing or touching

Checks the transistors. I think they are not correct

Thats the case, regarding your PCB murata`s, there is a place to solder centers for them, in my case there is not.

@tango - I got the idea now. only thing is where do I find GND?
This is how my PCB looked originally - http://imgur.com/a/CQH8f
I have circled with red two GND`s I am able to find. Am I good to connect to them?
Thanks

[tango]

if you look at the pic i edited of yours you will see where i made the gnd connection right at top
scrape alittle green away then put a little solder then use that space

So thats how it works .
Thank you very much!

EDIT:

While still on the topic, when soldering holes on KESS I think I messed up on this one - http://imgur.com/a/CGuQZ
Circled with red, it looks like both connections are touching. Is this really bad? Can I live with it? I tried to clean it up but with not much success.

Oh dear ......what did you use an oxy acetyne cutter to solder with ? ....

Yeah, it looks quite bad , this was the result of trying to remove the solder and re-solder it afterwards, but I messed it up quite a bit.
Im quite new in soldering, so...
Thing is what can be done? whats the best way to clean this mess up? I assume this can create short

Ok g00re, got it!

You can do it using solder paste which will clean the solder area while touching the solder iron and isopropyl alcohol to clean.
And lots of pacience!

Do you believe that they aren't the correct ones? This pictures was an example, I've ordered it from the same store, so it should be the same.
I really need to have the equipment in hand to see what I can do.

Thanks!
