    On the left side of the screen in the link I gave. They are not parallax, but are made with the same Linx module.

    Hi,

    The answer is quite simple :

    Some frequencies are allowed in your country ... and some not.

    Think to verify it before buying ...

    The frequency is the only difference.

    Here is a thread with some sample code

    The frequency and the allowed output power differ depending on the region or country. Europe uses 433.92MHz and allows far more power than is allowed in N. America.
