And same question for the XIAO nRF52840, Is it possible to use the DIO and CLK pads on the back of the XIAO nRF52840 as general purpose GPIO pins ?
Hi there,
I think it’s the same as this one we checked out ? YMMV
Something similar I’ll bet is possible or use the PLUS varriant also?

But that info is for the ESP32S3, I was asking about the nRF52840.
Different processor, different behavior.
Hi there , yes of course..
It’s the same want is what I was pointing out.

According to the nRF52840 datasheet,
SWDCLK and SWDIO appear to be debug pins.
They likely cannot be used as GPIO pins.

Huh? How about - “Oops my bad 
”
No, Not a Bad…
Trouble maker. 
WTF , is wrong "it’s something similar …I wanted him to go look and see , but that with the esp32 it IS possible , Is all. Go sell some peanuts or something…
As you were…

If you look closer and stop trying to find Fault always… The MCU name is in the Tittle
There is a “PLUS” in Both mcu family’s .The Bottom Line is THEY BOTH WANT to USE the BOTTOM PADS… or do we need sign language for you. 
Hi there,
and Yes, TRUE facts, I was hoping he would go look.
But the peanut gallery was wanting to chime in..So it is as I said.“MAYBE” or Not?
Thank you for the clarification.
