ESP8266

ESP8266 is a powerful and affordable WiFi-enabled microcontroller designed for Internet of Things (IoT) and wireless communication applications. It features a 32-bit processor running at 80 MHz (upgradable to 160 MHz) and comes with an integrated TCP/IP protocol stack, allowing direct internet connectivity without requiring an external WiFi module.

The module supports multiple communication interfaces including UART, SPI, and I2C, making it highly flexible for connecting sensors, displays, and other peripherals. ESP8266 can operate as a standalone microcontroller or as a WiFi adapter for boards like Arduino.

It supports development through Arduino IDE, NodeMCU (Lua), and MicroPython, making it beginner-friendly as well as suitable for advanced developers. Its small size, low power consumption, and budget-friendly pricing make it a popular choice for students, hobbyists, and professionals.
