When last I looked, some of them were under $4 US and about the size of your thumbnail.

RE

I am really tempted to buy, it only cost around $12 for a pair of receiver and transmitter module, but I can't seem to make up my mind. How do I assign a specific operating freq for the module? are modules the same as using Max232?


Tahe into account;

DC balancing of these receivers.
RF noise troubles.
synchronization problems.

lot more...
