NRF24L01+PA+LNA with Raspberry PI 3

[esawyja]

Hi all,
I have a NRF24L01+PA+LNA that I connected to a Raspberry PI 3 using the 3.3V output pin of the Raspberry PI 3, PIN 17 and it seems to work, but I have some questions about this

1. Would be better powering the NRF24L01+PA+LNA from a 5V pin on the PI with a 3.3V regulator, does the 5V pins output more mAs?
2. Rather connect the NRF24L01+PA+LNA to the PI supply power adaptor directly with a 3.3V regulator?
3. Does the NRF24L01+PA+LNA need a decoupling capacitor as well?

Thanks all

@esawyja My opinion, radio directly from psu and 3.3v regulator and yes, decouple the radio with capacitor.

Thanks, let me try that
