  • Seems to work

    posted by anode505

    Small, relay outputs
    Got this for while working on machinery, so I can jump out switches and such. The jumpers have a weird set up, with A&B on relays A&B latch, with just A or B jumper on, then the A&B relays toggle with just hitting the A button. (and outputs 1=D 2= C 3=B and 1=A, backwards) I just left the jumpers on, giving me 2 latched relays and 2 momentary one.
    Will save me a lot of walking around.
  • Very good item

    posted by marenas

    The device works in large distance. It is easy to instal into the breadboard. Stable signal is issued. Wide application, because there are four outputs with 3.5 V voltage. The standard operating frequency can be easily tied to the control module, standard RC remote control, thus allowing the device utilization.
    The device can be used to drive 5V relay. It can also be used as a simple one-way switch.
    The device according to their potential is worth the price.
  • 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.
  • Extremely Versatile and Fantastic Range

    posted by GreginOtago

    Has three different types of operation, select-able by a pin switch. This provides great versatility with the two buttons on the Remote. Remote has a huge range - I have it operating flawlessly over 50 metres to the receiver, which in inside a steel box and located behind a small berm (although the receiver's aerial is located inside a small waterproof plastic cap located at the end of the metal box - still impressive though!)
    So good, I ordered a second one.
    Very good value for money.
  • 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!
