I have two arduinos (one uno and another nano) with NRF24L0 modules attached to both and they are communicating between each other. All good.
However, I have a load of different ones and have switched them with the working receivers to test them but they just refuse to work despite the pinouts being correct.
Does the pinout vary between manufacturers or something else perhaps? What really perplexes me is that some of the modules I've tried are brand new (just taken out of the antistatic)

Any help would be really appriciated. Thanks
