ESP32 Power Source Inquiry

Can you show me the power source for the esp32?

flux

The ESP32 (designated as IC1) is powered from a regulated 3.3V source. In your schematic, this 3.3V supply is provided via the PP3V3 power net portal. That means the ESP32’s power pins (such as VDD3P3, VDD3P3_RTC, etc.) are connected to the PP3V3 rail, ensuring it receives the proper voltage.
Would you like more details on the power connections or the decoupling network associated with the ESP32?
