Hi, I want to program my ESP-12E using, USB to TTL converter.Software that I'm using Arduino IDE.Can anyone show me the hardware cicuit for it.
I don't think you can use the Arduino IDE to do this. Here is a guide to how to flash them. https://learn.adafruit.com/building-and-running-micropython-on-the-esp8266/flash-firmware
You could have a look at http://www.arduinesp.com/getting-started.
Or more specific to the 12E module Getting-Started-with-the-ESP8266-ESP-12/.
