Hello,
The pico sdk allows changing the speed dynamically.
I've had one run stable at 400 MHz for a frequency counter project,
executing from RAM, not from flash. It required pushing the core voltage
to 1.30V. The stuff does not even heat, and I did not check power draw.
USB serial was still
Sure! It might be worth checking if Raspberry Pi themselves has published
any analysis on this.

Thanks Matteo :-) I have NRF-PPK-2 so I can profile current / power
for various clocks with running NuttX if you like :-)

It appears this is selected at compile time using a #define in the SDK. I
would certainly assume increased power consumption, however the Picos are
definitely able to handle this increased consumption, as I would assume
other boards are.
I would say the approach would be no different than configur
