Hi,
I am testing the NRF24L01 modules ordered from:
https://www.aliexpress.com/
The strange is the NRF24L01+PA+LNA SMA Antenna works well, but the NRF24L01 doesn't with same code and same wiring, what could be the reason?
Thanks
Adam

NRF24L01+PA+LNA:


NRF24L01:

 

The NRF24L01 is an integrated circuit. It is used on several different modules of differing design from different manufacturers.

 

hi Adam,
The NRF24L01+PA+LNA SMA has a far superior specification than the early NRF24 types.
Check YouTube for users carrying out range tests, comparing the two devices.

This PDF is useful, compare the old and new types of PCB

 

You might have a knock off. I'm fairly certain the ones I have are another chip disguised as NRF24L01 made with an older process. Look up some images to see if yours match the benchmark, mine didn't.
