    I have ordered six so far and they have all worked. Sometimes the USB connector isnt quite straight but I have never had one not work. I use them both with the Arduino firmware and micropython firmware.

    Good so far... rcvd well packaged. Wish silkscreening for pins was better, eaiser to read. My first venture into iot and esp8266. Having problem with wifi consistently dropping offline after about 24 hours or so, despite setting up static reserved ip for both mcus and revising code to reinitiate wifi connection if it has dropped. Also have tried a discrete 5v power supply instead of usb power supply, with same result.

    These are a great way to build a small sensor board without needing a separate processor.

    I have been using mine for a year and its been great. I used it with mongoose os which it much simpler to use than arduino IDE. I love this little board.

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.

Note: Please contact us if you need the driver or meet any issue when using. We provide 100% satisfication service for customers.
