  • Easy DIY 433MHz antenna

    posted by JBSchueler

    I ordered a lot of these devices now. To get a good range I used antenna's from an other project. Easy to build your own.With an Arduino and the right libraries you can automate your home with ease. Works great with KiKa.Read this document to see how I make the antenna's. http://www.elektor.nl/StreamFile.lynkx?path=Uploads/Forum/Posts/How-to-make-a-Air-Cooled-433MHz-antenna.pdfI use these antennas also for the transmitters...
    None at the moment...I just bought some more ;)
    Really affordable so if you want to play with 433MHz transmitters and receivers, this is a good buy!
  • Great 433MHz transmitter

    posted by JBSchueler

    Amazing chep and great performance. Works straight out of the box with the arduino virtualwire. In the upcoming day I will check if I can connect it directly to the uart port of the arduino to have more easy communication. I want to use these devices for my home automation and I am not sure if they can reach over 50 meters?!? For now I used a 17cm wire but for better performance it should be probable tuned.
    I will sure buy more of these devices together with the cheap transmitters!!!
    Really a great product and easy to use. If you want to experiment with 433MHz, buy this product!
  • Nice and affordable transceiver, but beware of pin header pitch.

    posted by talosds

    * It's a cheaper option than most development kits.* Features a decent antenna (and the possibility to solder an SMA connector and use a better antenna)* Can be easily used in hobbyist RC projects.* Based on the CC1101, a powerful, yet affordable IC.
    * Build quality is okay, but there are some flux leftovers on the PCB that may require cleaning.
    It's a nice, affordable radio transceiver, appropriate for both hobbyists and professionals alike. Not FCC certified, so not suitable for other use but prototyping and hobbyist projects.If having a pin header with a 2mm pitch is not a problem for you, then you should probably go ahead and get yourself a pair of these!
  • VERY NICE Transceiver!

    posted by markjeffery2012

    VERY NICE Transceiver, I tested this unit with a RS232 (max232) converter connected to my computer, and a PIC16 micro controller, and the results were very good! I did not test long range, but short range showed good results! The +5V was a major turn on!
    I LOVE THIS SMALL and COMPACT unit! I WILL BUY A TON MORE OF THESE!!!! The testing of the unit was very simple and EXCELLENT!!!!
    You wont be disappointed in this unit for the price! The parts on the board are top quality and you cant build it for this price! I was looking for a cheap and easy solution, and i found it!!! VERY GOOD PURCHASE!
  • Excellent build, no manual or info

    Well BuildDont get hotAlmost plug and playFixed AntennaGood plastic body
    You need to discover drivers and files thru translation, all material in chinese.I didn´t got working yet...Should be a support file with manual, source cod example or compiled program.
    Really cheap, well build, but don´t know how to get working yet... I will install visual basic and discover all drivers, I thought it was a serial type of communication, but it uses .DLLShould be eazy to add a reference guide into this product.It seem to support development thru Windows or Linux, I didn´t found the libraries yet.
