The RAK4631 is designed for two supply voltages.
(1) a regulated 3.3V supply
(2) a second supply directly from battery (or USB/charger output). This second supply must be higher (preferred at least 3.7V) to have module working in lowest power consumption.
Ok, so basically the conditions are it will work from a battery from 4.2V down to 2V (on RAK19007), but power consumption will be significantly higher going below ~3.6V.
Correct?
