## Description

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

## Questions & Answers

**Q: Is this any different then the adafruit huzzah esp8266 breakout?**
A: This unit can be programmed directly by connecting a micro-usb cable. The huzzah esp8266 breakout requires a ftdi cable for programming. The huzzah feather is closer to this unit but costs about 20 dollars.

**Q: Does this dev board have an integrated power regulator**
A: Yes, it has a integrated power regulator.  You can supply 5V (via USB or board pin) and the system runs on 3.3V.  You can even pull 3.3V off the pin(s) to your external components, or supply 3.3V on the appropriate pin.

**Q: Is it meant to be powered by the USB port?**
A: While you can power it from any USB port, the point is after you load your code to the board it's wi-fi and can operate independently with a 5vdc power source. The ESP32 CAM modules are really cool. You can set up a 5 camera home security system for about $50.

**Q: do I just plug this into my Arduino Uno?  will it work with other stacked shields?**
A: Short answer: no.  But you can get a simpler (and cheaper, incidentally) esp8266 module (not the dev board) and use it to connect your Arduino to wifi.  I suppose you probably could rig this up to work, actually, but it would kind of be overkill, and would NOT work with shields.  A small basic esp8266 might be able to be worked into a proto shield for what you seem to be looking for.  There are several tutorials on using the esp8266-01 (this is the -12e) to connect Arduino to wifi.

### ⭐⭐⭐⭐⭐ Review
*by T***B on 11 May 2021*

Bought 3x NodeMCU ESP8266s; 2x for a specific project, and one for testing purposes. All of them arrived well packaged and working perfectly. Setup instructions on this Amazon listing for configuring the Arduino IDE were perfect, and got me up and running a blink sketch within 5 minutes. I currently have one sending hall effect sensor states to another, and displaying the state on a TM1637 7 segment LED display - I was able to get them to communicate via wifi (UDP) with no discernable lag at over 5 metres apart.
