[Radio] NTX2 USB and XBee mount breakout

So i like modularity. I think most creative people do. If you do not like modularity, it is probably because you like to take a complete product apart, thus making it modular. Indeed, modularity is the way to go, especially in DIY electronics, where i like to use my crap for various applications. Also, it’d be very expensive making a separate item for every project you work on. Also for debugging, modularity is nice.

This module will be used in my 5th High Altitude Balloon project due December 2011.

So i have made two modules, they are extremely simple, on a “beginners on electronics” level, a level in which i am comfortable (keep it simple).
So i used the NTX2 radiomodule by radiometrix, and i made a USB module for it, and a Xbee mount module. Both are displayed below, and very self explanatory. After soldering both together, they worked *instantly*. Life with radiotransmission can not be easier.

The PCB's front and back and assembled

The nice thing of both modules is that you can play with the variable resistors, so that you can change the frequency and shift a bit. I hate calculating and testing all kinds of resistors that never exist in the frequency that you want. So, can’t be easier.


So you can just hook this up to any computer or perhipial with a USB port. Then you use some terminal or whatever to talk to it, and it will immediatelly spit out that information over your frequency.

Kinda works like an xbee as well; you just send it some bits and it will spit out those bits.

Example of usage in a HAB payload: with a battery module, a GPS and the NTX2bee on a xbee mount that transmits the data.

Yeah so you can download the PCB Eagle files right over here:

  1. These look great – just curious, how did you get the PCB manufactured?

    Dear Tim,

    I would like to create a radio link over a range of 10 Km with two of your NTX2-Usb. Will it be useful for such a purpose? Both of the links uses Linux as operating system. And finally where can I buy fully soldered NTX2-USB?

    Best regards,
