AR9271 Ali Green dev board

Pin 5 on this board is described as “RF on/off” - “disable wlan rf when low, floating is not allowed (3.3V level)”
Not sure if I need to connect this or not.
(Picture that Sebastian Losche put on Telegram doesn’t show a connection)

I assume that either it works while floating despite the warning, or there’s a pull-up resistor somewhere.

Thank you yes - working fine!
