    Recommended by electrodragon as replacement for the ESP-12E module. Pin compatible, and it works great.

    Interesting module, easier to use on a breadboard than some of the other ESP12 modules

    My favorite module to build into any PCB for WiFi needs. Good price and always pleasantly surprised on delivery times.

    Can I program it via Arduino IDE – C/C++ programming language ?
    I’m using Node MCU V3 – 12E because it has Board choice in Arduino IDE but there is no 12F model.
    please give me to do list for program it in Arduino IDE.

    These modules are a nice replacement to the ESP-12E, and have 4MB of SPI flash memory. Some people prefer the ESP-12S which doesn’t have the bottom row of pins, however I like to hack on some of the extra pins if you really want to take the time to tweak the most out of these. I use a custom build of MicroPython for these; code available here and from the official project at
