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

Product description

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 20 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. 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.

Comes pre-loaded with Ciseco 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.

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.

Features:

  • Just 4 connections needed for transparent serial data mode (PWR, GND, RX, TX)
  • Supports network identifier PANID for communications into separate networks if desired
  • Facilitates remote Arduino/Xino over-the-air programming
  • Can be programmed in its own right (requires a TI cc debugger)
  • Supports serial bootloading (firmware updates without a hardware programmer and using just RX/TX lines)
  • 5v tolerant serial (can be used with a 5v micro without level conversion)
  • Acts in most serial applications as a drop in replacement for series 1 XBees
  • Made in the UK
Aplications:
  • Low power wireless applications operating in the 868 and 915 MHz ISM/SRD bands
  • Industrial monitoring and control
  • Wireless sensor networks
  • Wireless alarm and security systems
  • Automatic meter reading
  • Home and building automation
  • Low power telemetry

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.

  1. 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.


  2. Poor information, Excellent hardware

    Posted by Richard on 6th Jan 2013

    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.


  3. Once you know what these things do you will want more

    Posted by Magpie on 15th Oct 2012

    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.


  4. I love it

    Posted by Unknown on 22nd Aug 2012

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

    Think of more projects to use.


  5. Great product!

    Posted by Bi0H4z4rD on 20th Aug 2012

    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


  6. Easy to use as plug & play

    Posted by Andrey on 16th Aug 2012

    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!


  7. Works out the box

    Posted by Bill on 30th Jul 2012

    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.


  8. Fantasitc!

    Posted by Paul on 16th Jun 2012

    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".


  9. Love

    Posted by Jason on 2nd Jun 2012

    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!


  10. Third one I bought

    Posted by Quentin on 11th May 2012

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