I’m really sorry, but I do not fully understand, what exactly you mean with this. The voltage at the PPK2 was set to 5 V, as I was powering the XIAO at the USB port.
The way shorter pulse duration I was mentioning earlier was “measured” with the uCurrent and an oscilloscope. At that time, I didn’t have a PPK2 yet.
Or were you referring to a different response?
