3D Model and Pinouts for XTRX

Several people requested 3D model files for XTRX to make sure that boards they design have enough space to fit it in, so we’re publishing the latest version now that the XTRX rev4 design is finalized:

XTRX mostly follows the Mini PCIe standard recommendations for size, with the only the exception being a larger height of the top side. We couldn’t find a good RF shielding cage and good baluns to fit into the 2.5 mm height recommended by the Mini PCIe standard, so this part of XTRX has a height of 3.6 mm.

We’re also publishing pinouts for XTRX and its various connectors:

PS: Make sure you’re gettng the latest version of the docs from https://github.com/xtrx-sdr/xtrx-docs.

Get an XTRX Pro board. Does not include any cables, antennas, or adapter boards.


PCIe x2 Lite Adapter

This PCIe card securely holds an XTRX board (not included) so it can be used in a standard PCIe x4 slot. This adapter achieves the full 10 Gbit/s raw bus bandwidth and can be plugged into x4/x8/x16 PCIe slots. A six-pin JTAG connector makes it easy to program and debug the FPGA. Includes six SMA-to-U.FL cables, two screws for mounting your an XTRX board, and four 8 cm U.FL-to-U.FL cables.


Antennas + Cables

A full complement of cables and antennas for your XTRX, including four RF antennas (95 mm, 2 dBi, SMA male, GSM/3G/LTE 880 - 960 MHz, 1710 - 1990 MHz), one GPS antenna, and five cables.
