The ESP8266 is a low-cost Wi-Fi microcontroller, with built-in TCP/IP networking software, and microcontroller capability, produced by Espressif Systems [1] in Shanghai, China. The chip was popularized in the English-speaking maker community in August 2014 via the ESP-01 module, made by a third-party manufacturer Ai-Thinker.
NodeMCU was created shortly after the ESP8266 came out. On December 30, 2013, Espressif Systems [ 6 ] began production of the ESP8266. [ 12 ] NodeMCU started on 13 Oct 2014, when Hong committed the first file of nodemcu-firmware to GitHub. [ 13 ]

[3] [4] At a low level, the ESP Easy firmware works the same as the NodeMCU firmware and also provides a very simple operating system on the ESP8266. The main difference between ESP Easy firmware and NodeMCU firmware is that the former is designed as a high-level toolbox that just works out-of-the-box for a pre-defined set of sensors and actuators.
