The SX1261MBxAS board has a PE4259 RF switch.
The implementation for this board sets the pin to analog in (PIN_ANALOGIC
) when the switch is supposed to be turned off.

Lines 317 to 325 in 24d55f6
Per datasheet the CTRL/ pin (that this piece of the software controls) is also the V_DD, positive supply voltage pin.
Does this pin not need to be driven to LOW instead of floating to prevent the switch from drawing any power?
