    These are great little modules. Great for the IoT or just messing with people. I have one loaded with a fake wireless access point that I can power all day from a small phone backup battery that RickRolls people when they join it.

    Great little board. Definitely recommend switching to the Arduino IDE though as youll get more bang for your buck with the minimal memory it has. Be sure to watch out for the pin usage... having certain voltages on the pins caused mine to not boot and put it into other modes. Otherwise great little board for the money!

    I started with Arduino boards on some small projects, then I wanted to add WIFI capability to the projects. Initially I was trying to add wifi modules to Arduino, but I came across this ESP-12E board, and decided to give it a try. The package came with 3 boards, for about $14, very inexpensive in my opinion. I connected one to my Mac, and started trying the example sketches through Arduino IDE. This little board really surprised me with its capability, and it brought me many ways to expand my ideas on the projects, far exceeded what I had initially expected. I am in the middle of transfer all my projects from Arduino boards to this ESP-12E, and also on its successor ESP-32. I am very pleased with the purchase, and with many other components that I bought from HiLetgo. Finally, as some other reviewers have already pointed out, the CP210X USB driver needs to be installed (download at silabs dot com) on the host computer first, before Arduino IDE to be able to upload sketches to the board.

    These guys are cool! First ESP projects ive done. Used some with wled for kitchen light controller and some for my Christmas light display. Easy to flash easy to work with, hard not to get obsessed thinking what you want to build next.

    This worked great. Worked. Not so much now. There appears to be a soldering flaw on the board and it no longer communicates with the USB or several pins unless I hold my finger just right on the board. Other than this, I would strongly recommend it.

    If you are familiar with the Arduino UNO then you will have no problems using this board.

    Fun to mess around with friends and people at coffee shops

    This board is incredible. Its connectivity is lightning quick, it is programmed with the Arduino IDE and Syntax, and it has a built in USB Port all for a price lower than youd pay for any of that by itself. I built an app to control my TV with my Android phone using this board and an IR LED and Ive already bought a handful more of these for other things. Cant recommend enough and cant wait to use in future projects.

    Good product and easy to use.

Description:
ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained networking solution, allowing it to either host the application or to offload from another application processor.

Instruction & Steps of How to use:
1. Download the Arduino IDE, the latest version.
2. Install the IDE
3. Set up your Arduino IDE as: Go to File->Preferences and copy the URL below to get the ESP board manager extensions: arduino.esp8266.com/stable/package_esp8266com_index.json
4. Go to Tools > Board > Board Manager> Type "esp8266" and download the Community esp8266 and install.
5. Set up your chip as: Tools -> Board -> NodeMCU 1.0 (ESP-12E Module) Tools -> Flash Size -> 4M (3M SPIFFS) Tools -> CPU Frequency -> 80 Mhz Tools -> Upload Speed -> 921600 Tools-->Port--> (whatever it is)
6. Download and run the 32 bit flasher exe at Github(Search for nodemcu/nodemcu-flasher/tree/master/ at Github) github.com/nodemcu/nodemcu-flasher/tree/master/Win32/Release Or download and run the 64 bit flasher exe at: github.com/nodemcu/nodemcu-flasher/tree/master/Win64/Release
7. In Arduino IDE, look for the old fashioned Blink program. Load, compile and upload. 8. Go to FILE> EXAMPLES> ESP8266> BLINK, it will start blinking.
