ESP8266 NodeMcu ESP8266 Module ESP-12F NodeMcu LUA CP2102 Internet WiFi Development Board Works for Arduino IDE/Micropython

Why ESP8266:
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, Firmware link:;
The Data download access to the website:;
Test Video:
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:
Placing the “http://” before the URL and let 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:
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) Or download and run the 64 bit flasher exe at:
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.
