How to get started

[Lomagno]

No, I bought these RF 433MHz elsewhere. Could you please recommend specific modules that are compatible with KC868-A16 boards? I've made a brief search on the internet and haven't found a secure option. Please bear in mind that I need a very good RF range, something between 10 and 20 m away, on the floor above. As I said before, I am a novice to these products; I purchased these Arduino-style cheap ones to test programming and range, with an eye on the Superheterodyne, external antenna models. I have not bought the external antenna model because I noticed one of the modules has a 4-pin connector, whereas the KC868 has 3. Afterwards, I noticed threads in this forum that they may be used, despite issues with their compatibility, so I ask to please inform me which module to buy and/or the correct specifications to look for, preferably for best long-range RF.

Thank you. Have just ordered a receiver and transmitter modules and the RC unit. Hope the antennas come together with the modules.

You can weld a soft wire as an antenna.

If the antennas do not come with the modules, I will try soldering 17 cm of solid copper wire, eventually coiling it to reduce space and increase efficiency. This should make a quarter-wavelength antenna. Fortunately, the PCB case and electric panel enclosure are made of plastic, so the "Faraday Cage" effect would not be an issue.

yes, you can try.
