nrf52832 + rfx2401

[Stas]

(Hello! I'm drawing the module circuit base on nrf52832 with rfx2401 power amplifier (PA). 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

.

Hi,

Yes, with the nRF52 you can use GPIO pins 24 and 23.

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. See this blog post for more information on this.
