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.

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.
I ordered the superheretodyne 433 MHz sender and receiver modules directly from the Kincony store, but unfortunately, a shipping issue prevented the item from being delivered. The store is providing a refund, but if I understood it correctly, they do not offer to send the material again, which I still need. I am considering buying it from AliExpress due to its (usual) straightforward shipping procedures. Still, I am afraid of choosing an incompatible module, particularly regarding the sender module, which has four connection pins as standard. Kincony Store's module has only three connection pins (in fact, there are four, but one is cut, according to the images sent). I am sending an image of one of the AliExpress choices. Are these modules compatible with my KC868-A16v3 board?

Hi.
I am afraid of buying these modules on your online store because of the shipment problem I had with my previous order. I did not find these modules in your agent stores on AliExpress either. Would you advise me to repeat the order at your online store? Are the AliExpress modules (4-pin) risking compatibility? Please don't take me the wrong way, but I would not like to "try" a component. I would prefer to buy "the solution" instead. On the other hand, can you certify that the shipping problem will not occur again on a new order of the same modules at your online store?
