I am currently looking into building a custom RF transmitter. The commercial ones built for Arduinos usually operate at 5V. I was also looking into some RF remotes, and found that they usually use 12V. I am wondering if this creates a difference in terms of RF output power?
It kind of makes sense for Arduino modules to run on 5V since that is a voltage the Arduino can supply, but would using a 12V circuit improve the output power?
