    Hello everyone,
    im designing a new dongle, mostly for personal usage, it will fit my needs.
    Anyway, since i want to dump lion in favor of supercaps, i need to know the power consumption of the ic itself (the prerihpeal will be calculated).
    i cannot seem to find it in the datasheet.
    With a supposed absorb of 100mA, with a 2.7V 1F supercap (ideally) it would take about 12 seconds to discharge it to 2V, which is enough to deploy the payload (the ic works from 1.62V to 3.63V, so 2V-2.7V is good).
    Can someone with the trinket M0 measure its absorbed current so i can get a general idea?
