Unbelievable, simply impossible, but I need lots of time to explain…
CC1101 is universal, but module with antena circuit NOT
If you were in one thread and not in many, I would have everything at hand…
it is for sure 433MHz version
coils indicated by green arrows, capacitors = red arrows
module version for sub 1GHz band has really different filters section
in a purple rectangle is a must-have set and in blue is optional (but I didnt found it in Chinese modules).
Apart from all this, their frequency is printed on the modules, so they are easy to distinguish - 433M means module is dedicated to 433MHz band.
And the last sentence - why?
The need to use filters in the antenna path results from legal conditions present in virtually every corner of the world.
Ask @_Szczepan
Your module has a frequency of 433MHz, but I’m not actually sure which (433MHz or 868MHz) you really need.
