data output: High - 1/2 Vcc, Low - 0.7v
input voltage: 3-12V (high voltage = more transmitting power)
range (work at 5V): 40m indoor, and 100m in open air.
popular link is like this: MCU -> Encoder -> Transmitter ------
Receiver -> Decoder ->MCU,
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.
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 .
