    These are great for Arduino, but the 8266 is more powerful than the Arduino.

      How ridiculous – the ESP is no way more powerful than the Arduino – less bits, slower, less pins, less memory.

        Doh… ignore me. Was looking at my ESP-01 and realised the only place it was ‘worse’ than my Nano was in pins. In every other respect it kicks ass!

    I have flash your ESP relay board using nodemcu firmware for luna.
    But I could not work with Esplorer, it doesn’t communicate with Esplorer.
    My ESP8266 12E has worked well with Esplorer as I pushed reset button.
    But Your relay board ahs not get reset button.
    Pls let me know how to solve this trouble?

    I am looking forward to hearing from you as soon as possible.
