K868-A16 433 RF MHz receiver

[Razvan]

we have check, when no remoter button pressed, the DATA of RF receiver's module is almost 0v
when any remoter button pressed, it showed about 1v.
i think your RF receiver module is broken, next time when you order, tell the seller, we can send you a new one.

Thanks so much for the help, no need to send me another module I already ordered a few this weekend. One more question, what do you think about another RF reception module with antenna, can it be used instead of the one that comes with the standard board? Picture attached.
