RJ11-6p6c pcb socket

Hi Peter, finally managed to get the board prepared using the Molex RJ11 Jack_top. What I'm worried about is that pins of the jack are short circuit due to maybe too large soldering ring. I have attached the Gerber resulty as png file

. What's your advice!

Let me poke at it a bit, I just copied the pad size from the sparkfun part (because the data sheet was silent on pad size) and it looks like the part I used has a smaller pin spacing (which I find odd and thus worth checking). If it looks right, I'll reduce the size of the pad a bit. At present there is 8 thou clearance between the pads but that is a little small.

When I Gerbv it the mask overlaps, but the pads have a fine 7mil gap between them.

Try this one instead. I fixed a couple of problems, there was a translate in copper1 (which I just discovered a couple of days ago breaks putting the part on the bottom of the board), the holes were .040 where the datasheet wants .031 so I used the standard IC size of .035 and the pads were too close so I changed them to .068 (creating about twice the gap that it used to have at about 17 thou):

edit: updated the meta data so that it shows up in Inspector better (as type -top with its Molex part number). So you may want to redownload if you grabbed this already, although the only change is the metadata):

Can I pay you to do my fritzing?

I need a round layered pcb made. Id like someone with excellent electronics knowledge to reply with an email. It is very simple, I think maybe, ten connections from a drv8833 to a feather rfm95. Hard part for me at least comes in simplying everything which is not needed out. Thanks! I prefer an individual, broke electronics engineering student or the like who needs the money rather than a company.

Procedure to make incompatible parts changes to core parts?

Well I suppose the answer to that question is no... There can be no two parts with the same Variant name... even if you create a new part and save it with the same Variant name, Fz with add a sequential number to the end of the Variant name. i.e If you saved it as Raspberry Pi Zero, I believe the new version would be Raspberry Pi Zero 1... Default Variant name is "variant 1". But you can also give it with any variant name you want... like "Raspberry Pi Zero_Peter's New and improve version"... just kidding... you could call it "Raspberry Pi Zero (Rev 01)" or something to identify it as the latest version or that it is your version. Don't make the name to long or it won't fit in the inspector block and you won't be able to read the end of it. There is already a Raspberry Pi B(Rev 01) and a (Rev 02) in the RPi library. That would make it consistent... All the old variants will stay in the library, you will just be adding to it.

Thanks, I figured this must have come up before and there was a procedure that I just didn't know. I'll do updated versions of all the RPIs and submit them and see what happens :slight_smile: .

btw, although they are almost identical, you have two RPi Zero's (RPi Zero and RPi Zero-w). The w stands for wireless which has builtin WiFi. It also has a couple of minor variants on the pins...

Good to know, I think we only currently have the original (v 1.2) I'll dig up info an the W and make one of those too. I didn't know there was a pin change, I had assumed they were the same.

Not a pin change, just a couple of variants... don't remember what they are... There is also a built-in PCB antenna and solder pads for an antenna button. The breadboard layout is also a little different as it has a WiFi chip. You could Google Zero and Zero-w, some where they compared the two.

While you are baking... don't forget about the Orange Pi's, Banana Pi's, and the Nano Pi's... O'yea, the Tinker Board too by ASUS... :relaxed:

Bom dia. Sobre o sensor de corrente não invasivo eu não consegui encontrar o desenho correto para que eu colocasse no documento qque preciso. Com o termo que me falou na internet eu achei um mais não é o desenho certo do sensor. Você poderia me dizer oonde eu encontro o desenho correto dele?

Creating QFN-24 3.5mm x 3.5mm

Hi Guys,

I have a serious problem. I had designed an entire PCB around a QFN-24 pin (3.5mm x 3.5mm) layout on fritzing. But only on ordering the PCB i came to realize that the fritzing supports only 4mmx4mm and not the 3.5mm x 3.5mm kind. I am facing serious trouble here since, a small mistep is causing a huge problem when it comes to soldering the chip. Is there a way to create the 3.5mm x 3.5mm version in fritzing . I tried looking at all available parts but it does not seem to exist. Could someone help me to find it? or how to modify it?

You must be missing some letters because I can't see a 3.5mm QFN-24

What is the exact chip name, and where is the link to the datasheet.

Given the data sheet / package foot print it isn't a big deal to modify a footprint and make a new part, but as Old_Grey said we would need a data sheet. Google finds references of a sort to qfn 3.5mm but it seems to be stencils and implies a .4mm pitch (but all the package outlines I can see are .5mm pitch) so the chip and package datasheet that you need are the first step.

Try this one:

edit: replace with one with breadboard correctly defined ...

The pcb is a 3.5mm stereo jack as that is what the cable ends in. I think the pins are correct but of course don't have one to try.
