(1) What is the pin-spacing of the terminal blocks? Are they 0.1" spaced pads?

(2) Could you post a standard connectors list which you folks already use? I'm wondering what the make and model of the USB connector is, for instance.

Thanks!

The pin-headers J2, J3, and J4 are all 0.1" spacing.  Also the alternate USB holes.  See Section 2.12 for more detail and post there if anything is missing.

#3

Does anyone have a drawing of the PCB only, the current files do not have this detail

#4

No, we don't have a CAD drawing of the PCB assembly and all the installed or possibly installed components.  We have the coordinate drawing above to show where the key holes are located.  Let us know what you need to know beyond that and we will help.

Hi, It would be useful for users of the OEM U3 board who use custom housings to have board detail, including USB connector added into the 3D file. Only the board outline is required (pcb traces and surface mount parts not necessary) including the locating holes and USB and 8pin connector details. Although most of this information is there it's spread between the 2d drawings and the 3d files, it would be better to have this all in it one 3d file?

Next time we do some work involving CAD drawings we will see if we can get more PCB detail added to all the drawings.  One detail, though, is that the OEM board does not ship with any connectors and thus the connectors could vary with what the end-user selects, although the USB connector should not change much.

Very helpful, thanks!
