kizmit99, In fact, I don't know part number, gonna use uSD slot from ebay: https://www.ebay.com/itm/2X-CONNETTORE-SLOT-SCHEDA-MICRO-SD-14X15mm-PCB-SMD-TransFlash-TF-memory-card-cs/262993476886?hash=item3d3ba1fd16:g:VxcAAOSwZ4dZHukX More over, I couldn't find layout for this item, so had to draw it from blueprints provided by seller. Pretty tedious work have to say... :phew: |

The data sheet for that part (which I think this is a better link to: http://images.100y.com.tw/pdf_file/10-TFP09-2-12B.pdf) does show an area surrounded by a dashed line in the recommended layout. That area isn't described in the datasheet, but from others I've looked at (and from looking at the bottom of the part) I suspect that area is meant to be free of (at least) unmasked copper. Whether it should be free from copper altogether, I'm not sure. I think the concern is the little metal fingers and the exposed spring making contact with the board in that area... If it were me, I would route no traces through that area, and not even flood it with the GND plane. Best of luck with your project! :-+ |

How would you feel about sharing the DipTrace project with us, or at least send it to me and other interested persons through private messages? I'd like to play around with the layout a bit and maybe give more suggestions and I'm just too lazy to re-create the footprints and everything in DipTrace from scratch. I'm thinking of some things, moving some parts around, but I'd rather not suggest it only to see it's not actually possible due to part sizes. It's easy to recreate but still takes time, and your circuit is not complex enough to make it difficult to clone it from the pictures, if that would be a worry. |

Normally, caps and resistors pertaining to the oscillator are kept on the same side of the PCB, as close to the xtal as possible. |
