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...

What Dial Switch do in ESP8266-DEVKITC
guys,
I have ESP8266-DEVKITC dev board, and it has a dial switch. When I reached in documents, it said its for " Auto Download and Flow Control"
I don't know what that means, can someone please explain that to me?

ESP8266 UART with Arduino UNO
can i directly communicate with ESP8266 and UNO?
my friend did that and it works!
and also i saw some peoples saying i have to use logic converter.
what should i do?
why my friends circuit works?

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?

Re: ESP32-DevKitC-VIE 5V Safety!
so its totally okay to use relay module with my ESP32-DevKitC-VIE board! right? there is no current overload from the board for the relay and kill the board. cuz u said its directly pulling 5v from USB port, right? i just really wanna keep this board cuz i waited really long time for this board 😕. c...

ESP32-DevKitC-VIE 5V Safety!
heyy, i have ESP32-DevKitC-VIE dev board. i wanna control 19V 4.74A and i have a MOSFET Driver Module (as shown in the attachment) and normal 5V relay module (relay module doesn't have a optocoupler but it have freewheel diode). can you guyz suggest me which way is the safest to control the above me...
