Hi,
I am making custom hardware based on the design of the nRF7002DK.
I see on the reference design schematic of the DK PCA10143, the U50 RF switch control pin is connected to an N-channel MOSFET driven from a digital pin from the nRF70.
Wouldn't it be easier and cheaper to just directly connect the SW_CTRL0 pin to the control pin on the switch (with a pull-up/pull-down if needed)? Or there is a reason for power consumption or software implementation that makes it not possible to do that?
Best regard,
Phuoc
