EditVileda Relax

This page needs a lot of tidying up.

This page is for Vileda Relax.

There's also a report that Vileda M-488A has an identical board, so some information may be relevant for it too.

The board has the following markings on the silkscreen:

Someone wrote a blog post for Vileda A3 which has a very similar pinout.
