Beginners • Re: RP2040 power voltage readout?

Hi

I am running the RP2040 off of a 3.7v Li-ion battery.

Can I get the power voltage of the RP2040 somehow?

Or do I need to use a separate analog input?

It's a Seeed XIAO RP2040 I am using.

You have--in theory--the voltage. It's the battery output, which nominally 3.7v. Are you looking for the actual voltage (which will vary with the charge state of the battery), or are you looking for the current so that you can compute the power?

"Power voltage" is not a meaningful term. In a DC circuit, power is voltage times current. Usually given as W = v*i with W in watts, v in volts and i in amperes.
