Use the FTDI programmer to output the 3.3V instead of 5V. Thus, you can avoid the hassle of the additional circuitry in case of ESP-12E Dev kit.ĮSP8266 GPIO Pins are not 5V Tolerant. However, NodeMCU ESP8266-12E comes packaged with an in-built CP2102 USB to UART converter to program its flash memory.

You can follow along this tutorial if you intend to do so.

If you are using stand-alone modules such as ESP-01 or WeMos D1 mini, you need to use a FTDI (USB Serial to UART) programmer with the UART interface of the ESP8266 modules to upload the firmware as well as program into their memory. Uploading FirmwareĪll ESP8266 modules provide a UART interface to upload the firmware into the flash memory. In this article, I will explain the steps to program the esp8266 using Arduino IDE. Some of the standard community-supported firmware for ESP8266 are: In simple terms, each firmware provides a different way to manipulate the Inputs/Outputs of the module.Įven you can write your own, but you won’t be able to get the community support for it.

Uploading the Firmware to flash memory of ESP8266 ModuleĮSP8266 Wifi modules can be loaded with different firmware.

To program any ESP8266 module, you will need to perform two things: Speaking of programming esp8266, lets explore different ways to program this wifi module… ESP8266 Programming All you need is a simple USB cable to program the NodeMCU ESP8266-12E module. It comes in a completely packaged form, and also contains an in-built FTDI Programmer. Till Date, ESP8266-12E NodeMCU is currently the most practical version as it contains a lot of GPIOs. So, let’s first explore everything about ESP8266 wifi module… This approach will help you avoid the hassle of putting together different components with esp8266 module before you are even able to program it. In this tutorial, I will be using a development kit to program esp8266 wifi module which goes by the name of NodeMCU 12E. If you have ever programmed an Arduino, you just need an initial push to get started with esp8266 programming.Įven, if you have not worked with Arduino before, and only a know a little bit about C/C++ programming, you are well versed to ace the programming of esp8266.īefore we dive into esp8266 programming, you need to know about the different features and specs of esp8266 wifi module, which makes it stand out from the other microcontrollers. The tricky part is you don’t need to be an expert in the field of IoT to play around with esp8266.
