How does the 2-Pole DIP switch on version 13 ESP82266 Arduino expansion board work ? Answered
Hi, I bought a kit that uses a version 13 ESP8266 Arduino expansion board (shield). That version 13 is not a standard ESP8266 board.
It has an unusual 2-pole DIP switch on it that can be set to "ON" or "1-2". I need to understand what the 2-pole DP switch does and I need to understand the electrical connections it is connected to.
The information on the makers web-site is not very clear. ( see https://fineshang.gitbooks.io/esp8266-based-serial-wifi-shield-for-arduino-user/content/chapter3.html )
There are many instructables about the standard ESP8266, but I cannot find any details about that DIP switch in a version 13 ESP8266 arduino expansion board.
Can you please tell me where the DIP switch on the version 13 board connects to - the pin connections - and why it is needed.
