It looks right to me. See this datasheet:

http://www.mouser.com/ds/2/185/ed_ZX_20140804-461411.pdf

Note that the part reference is 'RD', which means 'reverser top mount'. The pattern on page 5 of the datasheet is applicable, I think.

Where did you pick  up Eagle Cad library file - for this USB connector on your PCB????

I created it myself based on the datasheet of the connector specified in the BOM.

Used the same footprint and connector in previous projects (including data lines) with no problem.

I think the one in the BOM is Hiroshi, not the Molex you looked at.

It is not important Mollex or XY - standard USB cable must work with it and in your case it will  NOT - it will smoke  :-DMM.
see this link and compare your Eagle cad library USB with this one from here :  https://www.sparkfun.com/products/12035 and open Eagle cad file and paste it to your PCB!!

Mike, that's a totally different manufacturer. All that matters for the cable is that the pins are the right order for the orientation of the socket. The part that Zapta uses is reversed so that you can mount it on top of the PCB and still have the cable oriented properly (to solve that problem where cables are 'upside down' on some phones, for instance).

Here:



I suggest you  look at the actual datasheet for that actual part from the actual manufacturer, and then you'll see that Zapta's layout is correct. Indeed, his use in other products without the smoke escaping suggets that he knows wtf he is doing with this, doesn't it?

I've attached the relevant diagram from the datasheet (I made a mistake before - it is page 7 rather than 5, but the  footprint is the same anyway). Maybe you could take a look at that before insisting it is something else?

Ok , noted, better I am wrong than PCB !!

Mike and anybody else, if the USB connector in the BOM is hard to get or confusing, feel free to change and send me a github pull request (and having a nice manual routing if you feel like).

EDIT:  in this project I am using the micro USB connector Digikey 609-4616-1-ND (different physical footprint) which has the 'other' orientation.

https://github.com/zapta/arm/tree/master/pro-mini/board

In any case, the USB connector should have through hole mounting tab, otherwise the SMD pads peels easily.

agh, already ordered this board from oshpark, but didn't know that an "special" usb connector was used here, will make sure to order the correct one :)

You can download Hirose lib from this link: https://github.com/chiengineer/Eagle-Libraries/blob/11e4a75bc9876ab7e70823fd5aa7b1fb6786185f/Connectors/con-hirose.lbr
and use.

Thanks Mike. I can see a footprint for ZX62R-B-5P but it doesn't have through holes or vias, just SMD peels. From my experience, this will peel easily. My footprint has holes but I still solder it as an SMD part with reflow.

BTW, is there a standard for the orientation of the USB cable connector in relation to the PCB or the outer enclosure of the device? That is, "this side need to be 'up'"?  I had cell phones with both orientation. Personally I prefer the narrow side of the micro usb connector to  be up in the normal orientation of the device.

Hello - SEE WIKI - https://en.wikipedia.org/wiki/USB
See numbering of pins ;
See Eagle which shows this pins ( if enabled in settings of Eagle !!)

What's the conclusion Mike, that it doesn't work out that it works but doesn't comply with some part of the USB standard?

Test it - you have the cable and the connector - take some other cable and measure + / - on connector pins.. to make sure it woks with different standard cables..
USB or Universal Serial Bus standard was designed in the mid 1990 to replace old standards like serial or parallel ports.  In our days the USB connector can be found in keyboards, printers, digital cameras, flash drives, external hard drives and almost all peripheral digital equipment.

Until now three USB standards were released:

–          USB 1 released in 1996 with speeds of 1.5 Mbps for Low-Bandwidth and 12 Mbps for High-Bandwidth;

–          USB 2.0 release in 2000 is the most used usb port at the moment at supports a maximum speed of 480 Mbps;

–          USB 3.0 released in 2008 in the latest standard who can support speed up to 5Gbps.

There are 7 USB connector types: type A, type B, Mini-A, Mini-B, Micro-A,Micro-B and Micro-AB. Type A and B has 4 pins, Mini and Micro A and B has 5 pin usb pinout.

Mike, what are you showing? I am somewhat confused since we know Zapta's original connector has the right footprint, is wired correctly and conforms to all USB standards. Are you  showing a different connector that he should switch to or what?

The question from Zapta was ;
BTW, is there a standard for the orientation of the USB cable connector in relation to the PCB or the outer enclosure of the device? That is, "this side need to be 'up'"?...,

Yes. It is as shown in the photo I posted before:



The USB logo on the connector should be 'up'. You put the standard or reverse connector on the PCB to do that (so the curved part of the connector profile is 'up'). As I noted, particularly on phones and tablets, where the component side of the PCB may be screen side or non-screen side, you often find the connector upside down in relation to the body. The designer should have used the reverse connectors.

An example of the 'wrong' connector being used is the Hudl. In the photo below, the bottom item is the Hudl tablet and the top one is an LG 40 phone.

Zapta - here more lib - Hirose : http://www.diymodules.org/eagle-search?text=Hirose+usb&type=dev%2Cpkg%2Csym&lib=usr%2Cstd&desc=1

And this is the one you are using in part list with trugh holes in pcb ?
