Slightly different board version

[DuncanStadler]

I have the same board as 2.1.15 but instead of saying YK201A V2.5 it says YK201A V1.1 Do you think that they will still work the exact same or is this considered a new board?

for some reason, my answer did not get published.
if hardware looks 95% the same, i would give 2.1.15 a try.
as always, only test with 2a cc power supply or charger as power supply.
you can always run autodetected (over rtt) to verify the 2.1.15 defines.
