Looking for "transparent" RF transceiver

[flotulopex]

I just want to take a few minutes to give a short feedback about the use of the AUREL RTX 868 FSK (650201343G). I receive the ones from LINX too (see post #1) but I had to finish the project asap so I took the ones that arrived first ;-)


Once I had set up my wired proto on the breadboards for 9600bps serial communication, I removed the three wires (RX/TX/GND) "implemented" the modules and...got into trouble.



Before I powered-up the proto, I realized the RTX modules need 3.6V max and most of my project are made for 5V (silly habit, maybe).

So I started looking around the internet on how I would be able to shift voltage levels and found, ie,the BSS138 level converter. But I also found in our forum some people asking why 5V projects would not simply be powered in 3.3V; that's true...why not?

Luckily all the components I use can be fed with 3.3V ; so I adjusted the PICkit's voltage and...it worked like a charm.

Connections to the modules are very easy (Pwr, Enable, TX or RX and data) and, what I always like, the PCB's footprint has a pitch of 2,54mm.


I tested the RF link over 180 meters across buildings without any problem.

Last but not least, the module proudly works with...?


Actually, I paid $ 12,50 per module (came from POLAND).

Voilà
