What does it mean FTDI module? ESP32-EVB doesn't have FTDI.

I have basic external FTDI which I plug to the uart0 !

But why? ESP32-EVB already has a USB-serial converter on-board. Why not just use USB cable to connect ESP32-EVB to your computer and program it?

It's to ensure it's will work because I want to make a custom board !

Ok, but there is already USB-serial converter attached to UART0 RX and TX... You will need to disconnect it if you wish to use UART0 exactly... Search for "USB to UART CAN" part at the bottom left part of the schematic here:
