Comment on Badger 2040 – Fast updating RP2040 based e-Ink badgeparentComments−whiskersOP4yYou can shut down power almost entirely with circuitry to trigger a wake from sleep when pressing a button. It's no RTC but a compromise we made to hit the price point and allow for a very long battery life!−jrockway4yOK, makes sense. I looked at the schematic and saw a lot tied to the regulator enable pin, and that compromise sounds great for the badge use case.
