As I understand it needs to set pins TXEN, RXEN to high level to activate this PA. Can I connect those pins to GPIO 24,23 for example .en-USTelligent Community 13Wed, 04 Jan 2017 15:15:00 GMThttps://devzone.nordicsemi.com/thread/72496?ContentTypeID=1Wed, 04 Jan 2017 15:15:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a65401e8-4251-4737-b12d-a7cad276da4fSigurd<p>Hi,</p> <p>Yes, with the nRF52 you can use GPIO pins 24 and 23.</p> <p>On the nRF51 there was a pin named VDD_PA that you would normally connect to the rfx2401 TXEN pin to select TX active or RX active. But, on the nRF52 you can use any free GPIO pin.
