433MHZ RF TRANSMITTER-RECEIVER MODULE KIT FOR ARDUINO / FUNDUINO

The RF 433 Mhz module works as a simple data link, that is, it only transmits information in one direction. It is still extremely useful in simple applications that do not require two-way communication. It easily connects to any microcontroller or encoder / decoder circuits, allowing us to have a functional RF link in no time. For simple remote control, we recommend using Holtek Semiconductor HT12D and HT12E ICs.
