3 Pcs ESP8266 NodeMCU MELIFE CP2102 ESP-12E WiFi Internet Development Board Open Source Serial Wireless Module for Arduino IDE-Micropython

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: http://github.com/nodemcu/nodemcu-firmware; The Data download access to the website: http://www.nodemcu.com; Test Video:http://www.youtube.com/watch?v=Gh_pgqjfeQc. 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 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) 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.
