What is the function of esp8266?
Correspondingly, what is NodeMCU esp8266 used for?
NodeMCU is an open-source firmware and development kit that helps you to prototype or build IoT products. It includes firmware that runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. The firmware uses the Lua scripting language.
In respect to this, what is esp8266 board?
The ESP8266 is a low-cost Wi-Fi microchip, with a full TCP/IP stack and microcontroller capability, produced by Espressif Systems in Shanghai, China. This small module allows microcontrollers to connect to a Wi-Fi network and make simple TCP/IP connections using Hayes-style commands.
The 30 pin ESP32 can be reprogrammed and has both wifi and bluetooth. NodeMcu is software that comes installed in a ESP8266 nd uses the Lua programming language but the ESP8266 that comes with NodeMcu can be reprogrammed via the Arduino IDE.
