Hello guys i use nrf24l01 with joystick shield but  if the switch is on 5v my nrf stops working, but joystick on the shield uses 5v, I saw so many guys using it with switch on 5v with no problem, but my nrf stops working. Please help. Or i will be have cut the vcc header of the nrf and solder a wire between vcc and  3v3 on arduino.

If it is the funduino shield, The NRF is always supplied with 3.3V.
The other NRF pins are 5V tolerant, so that should not be a problem.

Ah, this is obviously some strange usage of the word 'safe' that I wasn't previously aware of. (D.Adams)

I now own such a Funduino Joystick Shield V1.A and did some further tests.

The power supply for the NRF24L01+ only worked for transmission (2MHz 0dB),
even with a 10µF added to the power pins.

Adding an AMS1117 brought the NRF24L01+ to full operation.
