Hi guys, I made a basic sensor communication between 2 arduino nanos and 2 NRF24L01, then I wanted to expand the covarage area, so I bought 2 Nrf24l01 pa+lna ( same modul but with antenna)
I am sure with the wirings but whenever I try to plug in the usb of arduino( which connected with nrf24l01 pa lna modul) it disconnects with pc and I hear the "usb plugged out" melody.
I bought 4 of them so I changed every one so I dont think it is from the NRF module.
Everything is fine with little modul but with the antenna one, there is this problem, you know guys what the hell is going on?

riva, I connected them just like the NRF24L01(without antenna modul) checked 24 times
Okay then, how did you wire the nRF24L01? It needs a 3.3V power supply but the 3.3V output from the UNO does not deliver enough current so you should be using a separate 3.3V supply. Another option as mentioned above is the USB port cannot deliver enough current to drive your UNO + RF + whatever else you may have connected.
You definitely need a higher current 3.3V Power supply, or a 5V supply and a base module to plug your nRF24L01 units into, like the ones shown on that page. They have a 3.3V regulator and good bypass capacitors. They usually solve the "Nrf24L01 Doesn't Work" problems...
Riva & TerryKing, first I want to thank you guys for your opinions, today I delivered another 2 nrf24l01 pa lna moduls(which I think much more quality ones) . So I figured something;
When I integrate the antenna module to a arduino(receiver) and plug in to the PC, PC accept it and reads from serial, but whenever the transmitter is powered (gathering sensor info and sends it) the receiver on the pc disconnects.
I tried to feed the arduinos from 9V so Pc was independent for power, only reads the receiver. But still the same...
So I wonder how a module only disconnects itself from pc, when it receives data ?
