Soldered the 2 first boards and took some measurements to verify the functionality of the PMIC chipset. The output resistor divider of the buck-boost circuit is programmed to output a 3V voltage. I hooked up a small LIPO battery and checked the power rails.

It works! Next step is to verify the energy harvesting capability
