I have a PCB on which i am taking a 5v - 1A DC power supply , and again providing 3.3v to ESP32 through AMS-1117 3.3v. Basically things are not working on when i solder the esp32 on my pcb but things are working when i check it with NodeMCU version of ESP32 ( development board with USB connection ). My question here is , for a dubugging purpose ( to check the flow of my program ) can i connect the CP2102( USB to TTL converter ) to the esp32 ( RX,TX connections ) and a common Ground ( CP2102 Ground with PCB's Ground ) and get the data on the Serial Monitor on the laptop where CP2102 is connected.
I am attaching the image which will describe my idea more. Please guide me.
