Powering ESP32 bike speedometer
Posted: Fri Mar 01, 2024 3:18 pm
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 ESP32 WEMOS LOLIN32 V1.0.0 with a SSD1306 0.96" OLED display.
