Note:

To ensure the power supply to the ESP32 chip during power-up, it is advised to add an RC delay circuit at the EN pin. The recommended setting for the RC delay circuit is usually

R = 10 kΩ and C = 1 µF. However, specific parameters should be adjusted based on the power-up timing of the SiP and the power-up and reset sequence timing of the chip. For

ESP32’s power-up and reset sequence timing diagram, please refer to Section Power Scheme in ESP32 Series Datasheet.
