all ABOUT RF modules

[cuber18]

 have so many questions about RF modules.. how to implement it and how to use it.. my questions are the following..

1. Is all RF modules with RX that have 8pins and TX that have 4 pins similar?

2. If you're using PC as your transmitter is this a correct schematic for it?

3. And if you have LED MATRIX circuit for example, can you attach your receiver module to the LED MATRIX circuit to communicate with the transmitter? Just like in this schematic..

4. If you are using FSK RF module is the encoder/decoder IC will be different?

To those who can help me. Your effort will be much appreciated. =)

Thank you and Have a nice day.. ^.^

nakita ko yung 315Mhz and 433Mhz two different rf modules para hindi mag interfere... direct cable connection din ginamit nilagyan lang nang max-232 para pwede sa usb to serial cable.

yup! i really think na pwede naman...

thanks for the reply.. heheh.. yan po kasi yung design project namin.. making LED matrix display wireless.. gus2 ko lng ma double check the circuit of our LED MATRIX display if its fine and if i can direct connect it to my RF module..

no prob.
