315Mhz RF link kit


SKU: EF03036

weight:15g

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 sides. Whenever there is no 315Mhz devices around, you may use it as direct cable connection.

Availability: In stock
