Wemos D1 R32 uno

The board works with 14.0 and instal.wled.me But I am trying to get Moonshine battery working.

As in I am using a 6v battery in the barrel connector on the board

The board is not in esspresif32 3.5 but is in 5.1

I saw somewhere wled 15.0 beta Where is this? does it have updated boards?

Will the usermods_battery show my battery voltage which is apparent or maybe IO0 (zero)
but I do not think I could select zero

Thanks,
Papa Lanc
