Surprised nobody has mentioned the Pico2 boards (based on RP2350A or
RP2350B chips, instead of RP2040).

As of now, Digikey shows no stock on the Pico2 and doesn't recognize
the RP2350 chip as a product. Ditto Mouser.

The fast floats look great. I wonder how fast they are.

 
The RP2350 data sheet is 1347 pages!

read the part on how the build in buck converter needs a custom inductor

wrong with it

The polarized inducor is strange. I'd expect that a small shielded
inductor would work fine. It is interesting to have a switching
regulator on a CPU chip... near a 12-bit ADC!

The Pi designs struggle to save pennies and microwatts, which not all
of us care about.
