    I bought a set of these and I am able to program both of them tasmoto and only one of them connects to my local network. I can program the bad with with blink and other programs and works fine just no wireless connectivity. Update I as able to find info on fixing the second one and it works great, so giving 5 stars.

    Love these little thing. Where else can you get a device to do everything these do.

    Worked great for using along with a common PS4 project. Only turn it on when I need it so I cannot comment if it lasts running 24/7 but when I need it the device boots up quick. Very easy to use. No problems programming, I did choose a slower speed when writing to the device. Took about 30 minutes or so to write to it.

    Easy to use if you know what youre doing, low cost. Made a internet/Wifi bases smart assistant with it.

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

    [2018-07-20] Seller has reached out to me to offer replacements for these MCU boards. This is good customer service, and I will trust that I just had an anomaly in the lot that I received. If things dont work out, I will return to give an update, but at this time all is great with HiLetgo. [Original review] Bad quality in my lot of parts. I have purchased a few of these and a large portion have manufacturing defects. I have had to touch up solder on the USB connector on one because it wasnt making contact when the cable pulled down on it. The other is unfixable because the UART chip had its legs bent under when it went through the surface mount solder process. There is no way it was QA tested fully or visually inspected with this defect. It wont boot or flash. The photo here is AFTER I removed a large glob of solder off the edge of the part. Wish they had a little bit better QA

    Bought for my IoT project with Amazon AWS. I plugged in to my MacBook Pro with existing drivers. Flashed well on first attempt and started working like a magic. Id definitely recommend this product.

    I refunded this because of the micro usb connection not working (there was no blue light)

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.
