Our extremely popular easy to use RF serial data module with great range and XBee style pin layout. The XRF has now had over an equivalent of 40 million hours of run time in the field, quite stagering for something so affordable.
Provides an out-of-the-box wireless RF serial connection without any need for programming or end-user configuration, when we say plug them in and go, we mean it, they transfer serial data transparently without requiring any initial config.
Operates in the ISM bands (868 to 915 MHz) and that means it has a greater range than Bluetooth, WiFi or Zigbee sytle 2.4 GHz units that sport the same footprint (those things sold by Digi). That means it goes through more walls and reaches further. We have had reports of customers sending data over more than 3 KM using the standard supplied whip antennas out side. You should expect 500m + on the standard antenna.
Comes pre-loaded with firmware which enables the XRF to interwork with all other Ciseco RF modules, without any programming or configuration. You provide data one end and it appears on the other. All data packetisation, data checking, etc. is all done for you.
Makes use of Texas Instruments’ CC1110, a low-power System-on-Chip, which sports a micro-controller unit (MCU), memory, a sub-1GHz transceiver, and an encryption engine.
Ciseco provide a series personalities that can be used to specialise an XRF so it can become a dedicated sensor or actuator that communicates using Ciseco’s LLAP, a protocol that is as easy to understand as a text message or sending a tweet.
We have a range of sensors, actuators, support boards, Arduino shields, and Raspberry Pi add-on boards that when fitted with an XRF become wireless nodes in a Ciseco powered internet of things.
Limitations to use:
The XRF is not recommended or authorised for use in life support, surgical implantation, nuclear or aircraft applications or for any use or application in which the failure of a single component could cause substantial harm to persons or property.
Now shipping XRF v2.0
As of 27th November 2013 we are now shipping XRF v2.0 modules, these are based on the SRF v1.2 module. Althouth they look diffrent from the v1.5 they are compatible with the expection on some LLAP personalites, for more details see this blog post XRF v2.0.
Dimensions: 29mm x 25mm x 9mm (with antenna attached)
Detailed electrical and environmental specifications are similar as those for the SRF and can be found here: http://openmicros.org/index.php/articles/88-ciseco-product-documentation/259-srf-technical-data

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.

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.

Very small, works great, easy to use, very flexible !
Think of more projects to use.

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

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!

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.

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".

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!

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