[SOLVED] 2 X nrf24l01+pa+lna with RF24_PA_MAX
-
@mfalkvidd thanks for your reply.
If we want to ground it, can we use the gold base ? I guess that this part is grounded....I met some issues with PA LNA, do you think that it can freeze after a while, and powering the NRF24+PA+LNA directly on the nano ? It seems that after one month of use, I loss many packets..

@doblanch well the theory says it should be grounded so the signals induced into the foil can "flow" to ground instead to build up a current in the foil. (But make sure to just connect ground to one side of the foil, connecting on multiple points can produce a ground loop)
I havn't tested if the "gold" base is grounded, maybe just check with an multimeter?
Also i have fine results with grounded and ungrounded shield.The PA/LNA shouldn't be powered directly from the nano. The voltage regulator on the nano will probably not deliver enough current to stable power the PA/LNA modul on the high power settings.

@Oitzu Thanks. I will test it ungrounded first.
For the nano thanks also for your reply, it's great to have confirmation that nano can not really support NRF+PA+LNA with RF24_PA_MAX parameter, which is my case.
I hope , that powering direclty from a USB will avoid any more issue, that I'm hitting...
thanks again -

Keep in mind that USB is 5V and the nrf24l01+ takes 3.3V on VCC.
