    Works perfectly with EspEasy and Domoticz https://www.letscontrolit.com/wiki/index.php/ESPEasy, upload firmware, connect to your wifi, and after rebooting it, it is really simple to use it for switching 8 relays It just takes an HTTP call like:,,<1/0 On/off>

    Pretty nice device. Good design, perfect soldering, good layout. It's like a toy, nice to hold it in a hand. Comparely with Wemos modules, this one is more accurate. Module's datasheet, schematic are available in the net. This is useful in development. Personally I did not use lua with this device, I prefer Arduino IDE, works good.

    Easy to use by Arduino IDE. Use https://github.com/esp8266/Arduino and you are up and running in a matter of minutes. Use two mini breadboard for easy access.

    FOR THE PEOPLE WHO USE WINDOWS 7 AND COULD NOT RECOGNIZED NODEMCU BOARD AS DEVICE: I am using windows 7 and even if installed ch340g driver, windows could not recognize my board so i basicly get to DEVICE AND PRINTERS > USB-SERIAL CH340(right click properties)> hardware (section) > properties (button) > port settings (section) > Bits per second (115200 worked for me) > OK (button) If Bits per second 115200 did not work for you play with it for a while try different baud rates (But keep in mind the first one if nothing worked for you and change back to that one)

    to flash new firmware: 0) on windows/mac - download drivers (google it). No drives required on Linux (but use sudo) 1) download firmware https://github.com/nodemcu/nodemcu-firmware/tree/master/pre_build/latest 2) download esptool.py https://github.com/themadinventor/esptool 3) hold the 'flash' button on the board and run ./esptool.py --port=/dev/ttyUSB0 write_flash 0x00000 nodemcu_latest.bin 4) you can use ESPlorer to comunicate with it https://github.com/4refr0nt/ESPlorer

    The module pins were bent during shipment but I could mend it. First you need to update the firmware : look at those links for tutorial : -http://bbs.nodemcu.com/t/nodemcu-firmware-download-build-20150318-new-location/27 - http://www.electrodragon.com/w/ESP8266_NodeMCU_Dev_Board - http://bbs.nodemcu.com/t/nodemcu-firmware-download-build-20150318-new-location/27 - https://github.com/nodemcu/nodemcu-flasher Easy to have it work. Enjoy !

    While the base ESP8266 module is pretty slick as-is with the standard firmware, you can extend the usefulness of the built-in ARM processor using the open source work done by NodeMCU. This module is the 0.9 version of NodeMCU.com's dev kit for the ESP8266. It incorporates a standard ESP8266-12 module along with a CH340G USB<->Serial converter. The NodeMCU firmware is flashed to the memory in the 8266 using the nodemcu-flasher tool and you have an instant command line LUA language programming tool. This can be used to extend the 8266 supporting SPI, I2C and Arduino like digital and analog I/O using the GPIO pins of the 8266. Once the firmware has been loaded, you can upload and execute LUA scripts with the LuaLoader tool that is downloaded from Github. For all the tools and files, visit NodeMCU.com and click on the "English" link in the upper right hand corner, otherwise, you'll need to know Chinese.
