Re: What Dial Switch do in ESP8266-DEVKITC

Educated guess: Auto download will enable RTS and DTR to reset and put the chip into download mode using software, similar to what all ESP32 boards do by default. Flow control will connect RTS and DTR from the USB-serial chip to the corresponding pins on the ESP8266 so you can do hardware handshaki...

Re: ESP32-DevKitC-VIE 5V Safety!

alright!
so i have another question, i have Arduino UNO board too,
can I make a UART com between 2 boards, (Arduino UNO and ESP32-DevKitC-VIE (ESP32-WROVER))
by directly connecting jumper wires TX to RX and RX to TX
is that safe?
or I need some kinda logic level converter?
