Very cheap, can be easily used, even without arduino, works very well. There are a few noises being catch by the receiver, but I think that is unavoidable with RF transmissions. It seems that the default output voltage of the receiver (i.e., when not receiving) is half the total, and receiving brings it up to more 25%, making it not 100% optimal. Some ... Read more
They are cheap, for this price you can not buy any of these parts not just even the pcb.
It's small it's easy to connect to a microcontroller or to a arduino. It works with 2 power lines (gnd and +) and 1 data line(data in or data out). You can also connect a antenna to get better performance.
Well soldered. There is no problem with the soldering of ... Read more
Price is good for that, come into anti-static bag, easy to use. It's a good transmitter/receiver for the price. PCB of 2 pieces ins't so good( like antenna roles ), but acceptable for the price. This get too much interference/noise, but is usable with error correction, another problem is that this type of tx don't use a XTAL, seams that is a SAW filter ... Read more
Great little transmitter and receiver. Works perfectly with my Arduino's. Make sure you use the latest virtual-wire library. I've lost a lot of time with old libraries. So, point your browser to: http://www.pjrc.com/teensy/td_libs_VirtualWire.html Connection is great, although I haven't tested big distances. No cons. Now I know it works, I wan't more.... Read more
They have a good price for both modules TX and RX. They work perfectly with whatever microcontroler and any chip with a digital input. I have tested with a special chip for remote control and they work properly. My doubts were: the power. I have used 5V DC with them and finally they work fine. Perhaps some holes on the PCB would be good to set in other ... Read more
Communication with these modules is easy - you can setup your AVR board, connect and it's just that's it. If you need simple communication between your microcontrolers this is the way. You must solder wire as antenna for transm. and receiv. Without this your distance is limited to 0.5 m. With wire as antenna I have no problem to use two atmega8 boards ... Read more
It's cheap, it works on the original Arduino Uno R3, fast delivery. The two modulles come in an anti-static electricity bag. There is a lot of info on the internet, sample sketches, wiring diagrams, ... Receive interference from other devices, but for home projects certainly no problem. You must solder the antenna on the circuit board, no pin provided ... Read more
The "433Mhz RF Transmitter Module + Receiver Module Link Kit" arrived in a good package, i tested on an Arduino + protoboard, and after some googling it worked Not well documented, i spent a few hours on google looking for examples... -There is a big problem on the receiver module, mine came with the vcc and data inverted, and i just figure ...

Small size for both the receiver and transmitter.
The transmitter accepts a wide supply voltage range (convenient). The receiver really needs (only) 5V for good reception. This is a minor drawback however. A simple 78L05 can be used if only a higher voltage is available from on the receiver side. - To extend the range a 17 cm wire can be connected as ... Read more
Easy to use. The sender works nearly out of the box with my raspberry pi raspbmc with 3 Elro 433mhz remote switches. The sender has with the 5v of the Raspberry a wider range than the original remote. It is not really out of the box, but who buys stuff like that and doesent want to play a bit? ;-) Great for raspberry pi projects. I had to connect 3 ... Read more
