Flashing NodeMCU Firmware on the ESP8266 using Windows

If you’re new to the ESP8266 WiFi module, first read my Getting Started Guide with the ESP8266.

You can also checkout my other tutorial on how to create a web server with an ESP8266 running NodeMCU firmware.

Why flashing your ESP8266 module with NodeMCU?

NodeMCU is a firmware that allows you to program the ESP8266 modules with LUA script. And you’ll find it very similar to the way you program your Arduino. With just a few lines of code you can establish a WiFi connection, control the ESP8266 GPIOs, turning your ESP8266 into a web server and a lot more.

Downloading NodeMCU Flasher for Windows

After wiring your circuit, you have to download the NodeMCU flasher. It’s a .exe file that you can download using one of the following links:

• Win32 Windows Flasher
• Win64 Windows Flasher

You can click here to find all the information about NodeMCU flasher.

Flashing your ESP8266 using Windows

Open the flasher that you just downloaded and a window should appear (as shown in the following figure).

Press the button “Flash” and it should start the flashing process immediately (You might have to change some of the settings  on the Advanced tab). After finishing this process, it should appear a green circle with a check icon.
