Hi guys,
I use the crap receiver mentioned above. I’ve putted a 10nF and a 100nF capacitor between GND and VCC. As Antenna i use a steel wire with 173mm length.The Receiver is powerd directly from the PI(my Nano delivers only 4.7V!). What shoud I say… Receivers Range is now about 10m!!!Much better then without the capacitors(1-2m).
