These Simple RF receivers are the easiest way possible to add wireless control, painlessly!
Add wireless control to your next project easily and with no programming! This simple 315MHz 4-channel wireless reciever can recieve input from most 4-button 315MHz keyfobs and runs at 5 VDC. These modules make it easy to control your project once its in an enclosure or from across the room, but there are some things to watch out for. One is that they do not have 'addressing' - if you have multiple receivers in a room, they'll all work at the same time with a single remote. Another is that there's no error checking or bi-directional link - that means the remote doesn't know if the module received the message or not. Third, there are a few different types of receivers and each one looks identical but they're act differently!
The M4 momentary type acts like a push button - when the A button is held down, the matching pin goes high. When the A button is released, the matching pin goes low. The pins only go high when a button is pressed
