# 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.
