Usage:
The popular link is like this: MCU ‐> Encoder ‐> Transmitter ‐‐‐‐‐‐ Receiver ‐> Decoder ‐>MCU,
PT2272(Encoder) and PT2262(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.
Moreover, we will make more RF modules ourselves with different frequency and capacity. The next one in
plan is based on cc1100 Please suggest us about your need .
