Solar-powered autonomous development board that allows you to grow your project from a small seed to a big, beautiful flower.
AAA(10440) LiFePO4 battery as energy storage.
BQ25504 Ultra Low-Power Energy Harvester
A simple 1-to-3 buffered mult - Eurorack-talk for an audio/CV distributor
The board itself is a 3U 4hp rack-mountable module
This circuit was designed by https://www.skullandcircuits.com/utilities-buffered-multiple/ and their T&Cs apply to commercial use (I built these for myself)
