From the project
During the planning phase for my ULP switches, u/dynam1keNL posted about his mikefives, a radical new build that was diodeless, wireless, portless, and ultra-low power due to use of the Nordic Gazell wireless protocol among other innovations.

The ultra-low power design had me entralled and I knew I had to make a version of my Leaf Fold that builds in some of those features. This became the Leaf Fall.
