Been looking for an easy to use wireless module for your prototypes? One with superior range (upto 1Km), greater in building penetration, lower current consumption and lower cost? We think the XRF might be what you have searched for.

The communication of the device is normal serial, it transparently passes characters to and from XRF's. You don't need to do CRC's, any error checking etc it's all done for you.

XBee socket friendly 2 x 10 pin 2mm pitch layout RF module, in many projects it'll be a drop in replacement for series 1 XBees. Potentially this means your existing code needs no changes.

Out the box direct it just works, no complex setups, what you send to one appears on all the other XRF's. The packetisation, data checking etc is all done for you. Simply plug and send serial 9600bps data (many other baud rates supported)
Can specify a network identifier PANID to separate comunications into separate networks if desired.
Based on the Texas Instruments CC1110 combined micro & RF transciever, runs at 868.3Mhz, same chip can support 315, 433, 900 & 915Mhz
Over the air data rate of 250Kbps with a max of 500Kbps
Fits our XBS shield and XINO Pro boards and is a total drop in replacement for XBee
Can be programmed in it's own right. We suggest the free version of IAR's C compiler as there is TI sample code published on the web or you can use SDCC
Supports serial bootloading for firmware updates without a hardware programmer and using just RX/TX
Facilitates remote Arduino/Xino over-the-air programming
v1.5 now has 5v tollerant serial in so you can use with a 5v micro without level conversion.
Supports 128bit AES encryption like all the other devices do.

NOTE: new firmware supports 2 sleep states, the lowest being a miraculous 0.2 microamps.
PCB can support straight or right angled RP-SMA for easy connection to external antennas (new v1.5 supports end shot too)

good for a while

Posted by bryan on 3rd Mar 2013

I've bought x4 of these and two have died on me

I've spent years programming PICs and working with all manner of devices so I'm assuming its not me who is clumbsy but something systematic - I/O levels not sufficiently constrained to be 3V3

Anyway, I've abandoned them for a while and changed over to XBee(s) which seem to perform as described

why 3 stars? well I've tried writing a review with less but it fails to 'save'

CISECO: Keen to get to the bottom of this, can you contact us to return them to see why? Not sure why less stars fails to save, to my knowledge nothing prevents it.
Poor information, Excellent hardware

There is a lack of consistent information and gets shipped with none. While I understand this reduces costs, it increases frustration and annoyance.
Once working and the right links accumulated (there is lots of info on the web, here and there) the devices work well.
I now have 3 LLAP temp sensors working, a LLAP PIR, a couple of SRF's for lights and a USB receiver, all working quite happily.

By providing a little accurate documentation with the device or even a link to an updated document on the web Ciseco could be perceived as having good service, without it they may lose new customers.
Once you know what these things do you will want more

On recieving a couple of these I ran into problems getting them set up just how I wanted. However, the problems I had were down to lack of good documentation. In reality these little boards just worked, like right out of the box. I wanted to configure one as a button cell powered sensor, but again, trying to find out the best way to do that was difficult with the available docs. My problems were solved with one of the ciseco FTDI USB interface. Now I know how they work the docs become clear. I just keep looking for the next use of them.
I love it

Very small, works great, easy to use, very flexible !

Think of more projects to use.
Great product!

Well, just out of the box, it works perfect!

Except for a bug i found! If you run the ASCII table example found on arduino SDK with one of these, it will delete the flash, and a fw update will be required! This happened to me with a Xino board 4 times!

Should take a look at it!

Appart from that, i have even tried remote programming, and it works great!

CISECO - We will look into this
Easy to use as plug & play

This little devices are etremely easy to use. Just give at least two of them some power and you get a stable digital link. Very good price for quality product wich can be used in a great numbet of projects, wich require wireless connection. Thanks Ciesco!
Works out the box

I need reliable consistent comms on a budget and that's what you get with the XRF. They just work....and work well. Support is always excellent and delivery is fast. I've completely stopped using the alternatives now. Highly recommend having a play with LLAP on these using the Ciseco firmware downloads. Much easier than you think and very powerful.
Fantasitc!

I bought a pair of these last week instead of a couple of XBees and I'm very glad I did.

A fantastic product that "just works".
Love

All I have is love for this product. After-sales support by Ciseco is top notch. I wish there was more information on how to use the ADC in these chips without the need for a xbee socket; and programing them via a more novice interface like the Arduino IDE - But its early days and I am sure the products knowledge base and uses will only increase in functionality. They (yes - they - I couldn't help myself) worked from the box, and is a wonderful addition for creating wireless RC project prototypes at a low cost. Must buy, winner!
Third one I bought

I needed another one for a fixed wing model, works well no problems at all.
