Does RF Transmitter and Receiver able to transmit data (eg.hello) in open space upto 2km.
if more than one RF transmiter transmit the data ,does one rf receiver able receiver the data of more than two transmitter at a time
I assume that if the output is driven by a UART and the receiver inputs it into a UART that serial communication will occur. What is a good speed to use?
can multiple transmitters and receivers be used simultaneously in the same area (room)?
The transmitter/receiver pair worked beautifully. The documentation was pretty bad, but by reviewing the comments on this website it was fairly easy to understand how the units operate. Note that you are not required to adjust any of the encoding pin
What is the max output current per channel? Also, how much current does the receiver consume?
