    Update - needed to install cp2102 usb to uart bridge controller driver on my computer. This was not in the instructions. I got the IDE to list the board and I can select it, but sketches wont upload. Tried the flash thingy but I dont think it did anything. IDE does not show board on com port like my other boards. Instructions incomplete. Way too many hours wasted.

    These were pretty easy to start using. Just needed to study some YouTube videos to begin programming and to use in some very clever applications.

    There are some really weird quirks with this board. The first is the most obvious in that its a 3.3v device only. Meaning youll need to use an external power source for any 5v modules youd like to use with it. Next up is loading sketches. While it does work with the Arduino IDE software that other board use it takes a bit of massaging to get things up and running. Even more so if you want to use the serial monitor to view messages from the device. Finally the printed labels on the board dont match what the pin actually is. If you connected to the pin labeled D0 on the board and wanted to read an input you wouldnt read 0, youd read 16. Want to read D1? Thats actually pin 5. D2? Thats 4. D3? Nope its not 3. Its 0. That caused me more aggravation then anything else with this board. Make sure to lookup a pinout graphic if your working with this board and keep it handy. All that aside it works well, connecting to my wifi was a piece of cake with the included library and I was able to control my Philips Hue lights using this board and a library from Github. Not a bad board for IoT development, but far more frustrating than it needs to be.

    UPDATE: I first thought this board was defective, given the exact same behavior experienced in the reviews. HiLetgo reached out to me, which was nice. Their response didnt help, but once I got a good IDE up and running, the boards seem to work fine. So, user error I guess.

    These are excellent breakout boards, plenty of support libraries and projects to follow online for these specifically. No soldering required.

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.
