315Mhz RF link kit
SKU 113990017
Description
The kit is consisted of transmitter and receiver, popular used for remote control.
Usage
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.
Excuse for the documentation, we will work on them. Before that, please consult us for any
details, we are happy to find the answer for you .We tried them using the guide from Sparkfun,
it's compatible. The only difference is in package, of some excess GND pins.
