Esp32 Crystal Oscillator . What is a crystal oscillator? Introduction to the role and working "ESP32 does not support the use of main XTAL in light sleep mode, so an external 32kHz crystal is required." The external RTC clock source is used to improve the timing accuracy and thus reduce the average power consumption, but will not affect the functionality.
