MicroUSB is acctually recommended to be placed on the underside.
You will notice that when interfaced with USB chips as D- and D+ lines up.

Pinout names is for topview on toplayer, but moved to bottom layer it will be flipped around for correct pin out too.

The USB connector is this one: ... 2fag%3d%3d

Recommend to use Littlefuse SP0503BAHTG (a SOT143) for Vbus, D- and D+ connected to shield.
It's shown in picture and try to use the same layout as D+ and D- should keep same lenghts.
Use max 10uF cap on Vbus to stay within usb2.0 specs.

I am looking for a top mount micro USB pad. Any help with how you solved your problem would be helpful.

There are no micro-usb connectors in standard libraries. I will add them to list.

GCT offer a reverse (top mount) Micro USB connector, there are two varieties: USB3100 (pure SMT) and USB3135 (with thru hole shell stakes).

You can see more information here: ... /TopMount/

Note that to use the top mount variant you must cut out the pcb to allow the 'tangs' of the mating cable plug to mate properly.

Can anyone help me in finding and using the micro usb type b?

I`ve had a hard time searching through the dip trace libraries and installing new libraries... it`s a shame since it`s not explained anywhere (I had rapidly browsed through the diptrace website) how to install new libraries.. some have the same name but different size.

I am also looking for some mill max pogo pins; should anyone have any idea on what I am talking about, please point me to a component name / number.

Please have mercy...

Thank you,

a newbie
