XTRX Manufacturing Progress

It’s been a while since the last update and I’m sure you’re wondering what’s going on with the project.

Delivery Date Pushed to August

Bad news first - no XTRX delivery in May. :( Right now it looks like the realistic delivery date is end of August. We’re in the process of procuring components for the XTRX manufacturing and a vendor of our TCXO has suddenly increased lead time and set the expected delivery date to July 26th. Add manufacturing, testing, packing, and shipping and we’re looking at the end of August. That’s the unfortunate cost of using higher quality less popular components.

USB 3 Adapter Mechanical Design and Prototyping Complete

We’ve finished the USB 3 enclosure’s mechanical design, produced first prototypes, fixed a couple mechanical issues, and we’re now preparing it for production.

CNC'ed USB 3 enclosure prototypes

You may wonder how we could finish the mechanical design only now when we published images of the USB 3 enclosure design at the campaign start. That’s because enclosure design is split into two parts - a “visual” exterior design and an “engineering” interior design. The exterior design is when we argue on how to make something which you’d love to hold in your hands without compromising the heat dissipation, while the interior design is when we fight with the geometry and the laws of physics to fit everything we want into an impossibly tiny space. And that takes a lot of joint effort from designers, mechanical engineers, and electrical engineers.

A mock-up to verify that everything can fit (no USB 3 board yet)

USB 3 adapter PCB design is now finished as well (I still can’t believe it all fits in), and we’re waiting for a fab to manufacture the first PCB prototypes. The next steps are to verify a complete assembly and to greenlight mass production.

Testing the USB 3 enclosure heat dissipation, 64C is a great result

Feedback from Beta Testers

Thanks to the XTRX beta testers who started providing us with valuable feedback, there have been a few bug fixes committed to the various XTRX repositories recently.

XTRX beta samples before shipping

All beta units are in the hands of happy users, but it didn’t go completely smoothly and we had several quite stressful days. FedEx lost a package with a beta tester’s XTRXs! When one of the beta testers complained that he couldn’t track his package on the day after it was shipped, we didn’t pay it much attention. There was a snow blizzard in Boston and, according to a Boston tradition, the whole city was shut down (yes, even grocery shops, not to mention delivery services). When the package didn’t appear in FedEx’s tracking system on the day after the blizzard, we called FedEx only to hear that they didn’t have the package. The package was clearly gone from the pick up location but FedEx kept insisting they didn’t have it because it’s not in their system and their couriers don’t make mistakes like that, and that there is nothing they could do to help us. We tried to politely argue with them only to hear back that they can’t help us. Fast forward several days, we gave up and filed an official claim as a last resort. Suddenly, the package was found in a matter of hours. We learned a valuable lesson – file an official complaint first, argue later.

Product Choices

$260

XTRX

Get an XTRX revision 4 board. Does not include any cables, antennas, or adapter boards.


$515

XTRX Deluxe Bundle

Get an XTRX revision 4 board as well as an Antennas + Cables set, a PCIe x2 + Front End Adapter, and a USB 3 Adapter with Aluminum Enclosure (see below for details). Also comes with four extra U.FL-to-U.FL cables and four extra U.FL-to-SMA-male cables.


$59

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.


$79

USB 3 Adapter with Aluminum Enclosure

This adapter converts your XTRX from Mini PCIe to USB 3 and comes with an aluminum enclosure designed specifically for XTRX. The adapter has three status LEDs, a micro USB 3 port, one SMA connector for the GPS antenna, four SMA connectors for the MIMO Tx/Rx antenna pairs, a micro SIM card slot, and a slot for a GPIO FPC cable. Comes with a USB cable and all RF cables for internally connecting an XTRX to the SMA connectors. Does not include an XTRX, antennas, or FPC cable.


$99

PCIe x2 + Front End Adapter

This PCIe card securely holds an XTRX board (not included) so it can be used in a standard PCIe x4 slot. It includes an RF front end with a LNA and PA for up to 100 mW output on each channel. A TDD switch is incorporated for applications like TDD LTE. You can bypass the front end by attaching cables directly to XTRX. 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. A micro SIM card slot is also present.


$2,900

XTRX PCIe Octopack

This single PCIe card comes loaded with eight (8!) removable XTRX boards, metal installation brackets, enough cables for all GPS and MIMO Tx/Rx ports, and a special board for synchronizing all eight XTRX boards.


$1,900

XTRX Beta Tester

Here's your chance to get an XTRX board as soon as possible. We'll send you an XTRX revision 3 board as soon as the campaign reaches its funding goal and we'll follow up with a production version (revision 4) as soon as they come off the assembly line.
