I have seen this and i am wondering if any one has used it before and if not what they think of it.
Website i found it on and would likely purchase it from

Don't know about the product, but looking at that store, it's relatively overpriced.

Also, i have used the Xbee radios ( a bit more expensive) and absolutely love them.

More like save $2!
Those sparkfun prices are in usd, the little bird electronics prices are in aud.
the conversion rate is about .8-1 now so not much price difference, and as joker said. The shipping is hell from usa.

And i forgot to take into consideration the conversion rate.

You got that right smash :D

Gentlemen, quick question on this and the XBee circuits...
If I connected one of these to a simple push button switch, can I transmit a simple pulse?
The idea I have is that I would like to be able to push a button that is connected to a SCR, which is then connected to something like this that will transmit a signal until I turn my switch off.
On the receiving end would be a similar circuit that once it receives a signal turns on a red LED.
I'm still in college and really just begining to learn about circuit design which is why I ask such a simple question.
Thanks.

I don't have alot of time at the moment but this should help you for now.

That is just the answer I needed. Looks like I'll have to get me about 4 - 6 of these little guys then for my projects.
Thanks for the info.

no probs, glad it helped. ;D

A client asked me a year or two ago to implement Nordic transceivers into his project. They weren't really plug-n-play, somewhat overcomplicated really. I convinced him to move to bluetooth, and all were happy :)
If you have to worry about more than just power, ground, Rx, and Tx, its not friendly enough :P

The only thing I'm worried about is creating a sort of remote "stop" signal for when I do group rides on the motorcycle. That way when someone in the back of the group sees something that the group should have to stop for, he can hit a switch and every biker in the group who has one of these little boxes will see a red LED come on and know they have to pull over and stop cause something is wrong.
Or at least that is the idea. With school and what not I have not had time to research this nor the money to order these things to build samples with.
