    Retired Product

    This product has been retired and kept here for reference.

    This package consists of two half-duplex wireless data transceiver modules and each module is highly integrated with an MCU and a powerful RF chip. These modules boast features such as selectable channels, ultra long transmission distance (1000 meters)  and abundant interface options (UART/TTL,RS-485&RS-232). The software application ("RF-Magic") is offered for free so that users can modify the settings of the module. This is a popular module thanks to its ease of use, slim size and wide power supply range.


    Features:

    • Size (only PCB) : 39.60mm(L) X 19.30mm(W) X 4.32mm(H) ±0.2mm
    • Ultra long transmission distance: 800-1000 meters @1200bps
    • Working frequency: 431-478Mhz (1KHz step)
    • +3.3-5.5V wide power supply range
    • -112dBm(9600bps) high sensitivity
    • Over 100 channels
    • GFSK modulation
    • Highly efficient cyclic interleaving error correction encoding
    • Flexible software program option settings
    • Selectable RFID index
    • UART/TTL, RS-485 & RS-232
    • Large data buffer: 512bytes
    • Suitable for massive data transfer
    • Built-in watchdog ensures long-term operation

      Great set of transceivers. Easy to use, simply connect power & earth pins and tx/rx and send and receive your data. It did take a lot of searching to find the correct "RFMagic" program to change their configuration. Graham could possibly put a link on his page. It is http://sure-electronics.net/download/ then select RMB-CM12111 from the drop down. (Posted on 3/04/2016)

      These RF modules are a pleasure to work with.
      They are very easy to hook up, and for normal use require no calibration. Working with Bluetooth modules in the past I know how much of a pain they can be to get working, these were a completely different story.
      With the standard 0.1" pins and compact size they are easy to prototype with on a breadboard.
      I used them to create a wireless serial connection between Arduino to Arduino, and I couldn't believe how easy it was, just plug and play.
      I was able to get a range of 500m from indoors to outdoors, and I was quite impressed.
      If you are looking to add some wireless capability to your project, don't use Bluetooth, instead spend a little more and get these, you won't regret it. (Posted on 29/03/2013)
