    This is another thing where if you are buying it you already know what it is. And its exactly that! 2 ESP8266 NodeMCU dev boards. No issues encountered.

    Bought 4 of these, but only 3 worked. The one that did not work had the dreaded Serial port I/O garbage and no WiFi issue that others have reported, rendering it useful for only being an expensive LED blinker. The three that do work seem to be working flawlessly.

    Bought this node for wifi jammer project for my school and could not be any happier. I could plug this into my Samsung s8 with adapter for power and it made it so much easier to use as well as for demonstration purposes. My instructor was also impressed therefore I have no complaints about this product and would recommend it as it is solid build and works as advertised.

    These are fun. The board is overpriced, but you get them much faster. If you have time to wait a month, they can be ordered from China for about a third of the price. I was happy to pay extra and get same day delivery. Well constructed and easy to program. Hooked it up to an 8 channel relay board. Let the fun begin :)

    Works as it should. Supports many programs and services. It also has useful LEDs to check the status of uploads, downloads, connections,etc.

Product 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 all networking functions 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: http://arduino.esp8266.com/stable/package_esp8266com_index.json Placing the http:// before the URL lets the Arduino IDE use it...otherwise it gives you a protocol error.
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.
