It can be compatible with transmitter with 2262 chip ，315MHZ ，and 1.5M Timing resistor

Warning: this kit is not suitable for data transfer but remote control. Safe for 2 commands/second

Encoding and Decoding :

The popular link is like this: MCU -> Encoder -> Transmitter ------ Receiver -> Decoder -> MCU

PT2262(Encoder) and PT2272(Decoder) are optional, their existence is to 1)avoid confusing when multiple RF links in range 2) isolate disturbance. You can integrate the encoding and decoding work to the MCUs on both side. Whenever there is no 315Mhz devices around, you may use it as direct cable connection.
