Hi. I'm making a bike speedometer with ESP32 and everything is ok. but i don't know how I'm gonna power it. One of challenges is that I should be able to charge it while esp32 is in sleep mode or when it is active and i also want to show battery level on display. I'm using a ESP32 WEMOS LOLIN32 V1.0…

Have you considered adding a generator circuit using a bike lite generator?
