Hi guys, can anyone give me details on this rf remote used for running a motor. I need details like at what frequency it runs and which receiver shall i use to replace the existing receiver in motor. I am a newbie in electronics.
The commercial product from which that board was extracted had to be certified for compliance with government RF regulations. The details will be in that certification document. The frequency might be 433 MHz.
That is a big ask. Why do you post three pictures of the front of the board and none of the back?
There's a part on there with 433 written on it, so it is probably a 433 MHz carrier.
Beyond that, whatever is happening is baked in to that board, and could use a variety of transmission types and protocols.
Often with 433 we see proprietary methods, or I guess it would be more accurate to say we don't see them.
Which is why you need to find a Reverse Engineer and figure it out, if you are the first.
If that link makes any sense, you can learn enough to google more if it doesn't solve the problem.
For us, knowing as much as you prolly do about what this device is, like manufacturer, make and model, might spring loose some knowledge or experience or inform our own researches.
TIA

The numbers mentioned on the board is not clear in some pics so thats why
That is half the answer, "why did you show the front 3 times"... you didn't answer the part, "and none of the back".

Visit the local radio amateur club. They have the knowledge and possibly also a radio measuring station.
