Hi

I am writting to know if someone knows how to connect the attached receiver (https://www.seeedstudio.com/433Mhz-RF-link-kit-p-127.html )
with the"PT2262"(Decoder) ?
I need this for the popular link is like this: MCU -> Encoder -> Transmitter ------ Receiver -> Decoder ->MCU.

The attached diagram picture doesn't contain"PT2262"(Decoder) inside. We have to add some resistances and elements to the attached diagram with the decoder.

What I would like to know from the"PT2262" decoder datasheet (attached in this email) for my combination "Receiver -> Decoder ->MCU" is:
1) Should I use the schematic from p.10 or p.11 ?
2) if I would need to use the "MPSH10 transisor+inductor(10uH)+capacitors(5P and 25P)"?
3) If I would have to use the 47 KOhm resistor from p.10 or p.11?
4) If I would have to use 2.7KohmX4 resistor and 10KohmX4 resistor from p.10?

Thank you

 

Well the encoder/decoder chips are optional. You can encode the transmitter with the MCU directly using serial data and decode using the same procedure at the receiver. The 433mhz kit is all you need. The PT2262 and PT2272 allow you set the address pins to match each other as a security code. You should be able to program such a code or qualifier with the MCU. Also the PT2262 is the encoder for the transmitter not the decoder for the receiver.
