Where can I get proper tech specs for Nano Every?

The documenation on official website is conflicting, for example Arduino Nano Every | Arduino Official Store says

DC Current for 3.3V Pin 50 mA

but https://docs.arduino.cc/hardware/nano-every says

DC Current for 3.3V Pin 20 mA

So is there like definitive source with 100% correct tech specs?

But wait, 3.3V comes from AP2112K regulator https://www.diodes.com/assets/Datasheets/AP2112.pdf

The AP2112 is CMOS process low dropout linear regulator with
enable function, the regulator delivers a guaranteed 600mA (min.)
continuous load current.

Why such discrepancy? @pert

Maybe the 20ma is for the I/O pins, the 50ma is for the dedicated 3.3V out pin, and 600ma for the output of the voltage regulator.

Erm, no

Probably de-rated due to PCB heatsink limitations.

I looked into many Arduino boards and mostly the documentation says 50mA for the 3.3V output pin. That is just a number that is on the safe side.
I think that your guess is just as good as my guess. There is no definitive answer, and there are no guarantees. If you need 500mA and it does not get hot, then it is okay.
