how to choose compatible arduino

which arduino is compatible to use in panic button controller-link to wireless module.
in my project, i will use maybe +-40 unit transceiver, 1 panic button i have 1 unit arduino, 1 unit wireless tranceiver 2.4ghz and only have 1 receiver

That question is impossible to answer.

There are a number of official Arduino boards, some very common, some for specific tasks.
There are clones that are (almost) like the official boards.
There are boards that are Arduino-compatible, but are not the same as the official Arduino boards.

Is it battery operated ? What kind of battery ? Is it okay to use an additional board to upload a sketch ? How big is the sketch ? What kind of transmitter are you using ? Could you make your own Arduino-compatible board ?

What range transceiver will you need?
