Connecting ESPDUINO (ESP-13) to Arduino IDE was the most helpful place to start. You need to

  • open the Arduino IDE
  • Open ‘Preferences’ menu under ‘File’
  • Add the url to the ‘Additional Boards Manager URLs’ input box
  • click ‘OK’
  • open menus ‘Tools’ -> ‘Board’ -> ‘Boards Manager’
  • find the esp8266 by searching in search filter input
  • Click the esp8266 and click install

You should then be able to connect to and upload sketches to the espduino board.
