# pmod-numato

This adapter is useful for the following;

* Adapting the "XADC" style to the "HS" style.
- See [my high speed Pmod sheet for details](https://docs.google.com/spreadsheets/d/1D-GboyrP57VVpejQzEm0P1WEORo1LAIt92hk1bZGEoo/edit#gid=725118408).

* From from Numato's spacing (0.3145 inch, pin to pin) to
Digilent's spacing (0.3 inch, edge to edge).

The traces in a diff pair have been length and skewed matched with a tolerance
of ~1 mil.

The diff pairs as a group have been length matched to 0.8537 inches (21.6mm)
long with a tolerance of 20 mil (0.5mm).

To use Numato spacing device on Digilent host;
* B side should be up.
* The XHS side should be loaded with pins.
* The XADC side should be loaded with socket.

To use Digilent spacing device on Numato host;
* A side should be up.
* The XHS side should be loaded with socket.
* The XADC side should be loaded with pins.

# Board Manufacturing

* 5mil (0.127mm) trace width
* 5mil (0.127mm) trace clearance

* 12 mil (0.3048mm) drill size
* 6 mil (0.1524mm) annular ring
* 24 mil (0.6096mm) via size (6mil+12mil+6mil)

* 6 mil (0.1524) silkscreen width

This can be meet by;
* [Hackvana by requesting the 5mil option](https://docs.google.com/document/d/1p6FH25ltGpzJQ5_8fbflDukqEKghiEcpuhJpngth2Is/edit)
* [OHS Park's Four Layer Boards](http://docs.oshpark.com/services/)
