433MHz sender and recievers

[Fleetz]

I already have these 433MHz sender and reciever modules are these suitable for the KC-868-A4?

Or are the sender and recievers that Kincony sell designed specifically to work only on the KC-868-A4 board?

your photo can work with KC868-A4, just low quality, have much noise.
KinCony's RF sender and receiver module quality is better.
