Help with understanding ESP32-S2FH4 schematic
Can someone please tell me what the purpose of SW1, SW2 and LED1 is in the case of this schematic:

Thank you.

I need help with the ESP32-S2FH4 SoC
I'm using the ESP32-S2FH4 which apparently has embedded flash memory. I'm unsure what to do with the VDD_SPI pin on my PCB schematic. I found an example here of someone using the ESP32-S2FH4: https://www.wemos.cc/en/latest/_static/files/sch_s2_mini_v1.0.0.pdf They have the VDD_SPI pin connected to a...
