How can I reflash the ESP32 on it ? Can I do it through the USB port ? If not how ?

Thanks

Thank you for your replay!
Can you tell me what's the point of place R16 10k and R14 0R together? If R14 is placed, driver U5 will be enabled always.
How can I switch beetwin RS232 and RS485?

RS485 RS232 cannot be used simultaneously and does not require SWITCH. Originally, I wanted to use OE to disable the 485 function
