Hello, i have a few questions about this kit:
1- This kit is used for one way wireless communication at a frequency of 433MHz, but, it could be possible configure it for another frequency? I mean, if i had 5 wireless kit in the same room controlling 5 devices independently, i could work with 5 different frequencies?? An alternative??
2- The receiver power supply, Which kind of power supply has it? How much time can that receiver send 5V to -for example- a Grove Led with non stop? Is it easy to replace?
