GPIO47/48 voltage

[higaski]

I've a suggestion regarding GPIO47/48. On some S3 boards (e.g. the wroom-2) those pins only have 1.8V working voltage. This is mentioned on page 12 in the Wroom-2 datasheet.

Thank you for this repository, great overview of the S3 pinout!

My thanks as well!

I just came to add this as I happened to come across that datasheet note. Apparently those pins are probably not 3.3V tolerant, so this is a pretty big item on affected versions.

I'll take a look - sounds like it could cause some horrible problems!
