This adapter is useful for the following;

  • Adapting the "XADC" style to the "HS" style.

  • 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.

Questions

How big is the Pmod adapter PCB?

It measures 20.3 × 86.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Pmod adapter use?

32 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Pmod adapter KiCad files?

From the mithro/pmod-numato repository on GitHub, at the commit this page was made from: the board is board/pmod-adapter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Pmod adapter design in my own project?

Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
