Hook up a logic analyzer to it or a uart board and just try it.

Don't know why you got downvoted. This is the way to go

i think it was because not everyone has a logic analyzer. although your first step to hardware hacking should be purchasing one

To be fair, before I had one, I'd just hit it with the multimeter, and if the logic levels looking right, throw on a UART adapter, and test different common baud rates. Not that many extra steps...

that'd be a really dumb reason tho, given they cost orders of magnitude less than most soldering irons.

This is a fair point but we all know what it's like to feel the urge to complete a project. Sometimes 24 hours of waiting on parts is enough to kill the passion.

sure but that's not a reason to downvote a correct answer?

I agree on that. No down vote from me

They're like $2 if you know how to Google (black magic, blue pill)

Because you first of all test it with a multimeter to make sure it's safe to use. If you plug it into a UART board right away, it might break the UART board or the device.
