About this item

The ESP8266-01 is a compact, low-cost Wi-Fi module widely used to add internet connectivity to various electronics projects. It allows devices to either connect to an existing Wi-Fi network or act as a Wi-Fi hotspot, making it ideal for IoT applications. With the ESP8266-01, you can easily enable your project to send, receive, and process data over the internet. One of the standout features of this module is its compatibility with the Arduino IDE, which simplifies programming and broadens accessibility for hobbyists and developers. However, the ESP8266-01 has a limitation: it only provides two GPIO pins, which restricts direct interfacing with multiple sensors or peripherals. Because of this, it is often used alongside an external microcontroller like an Arduino, or users might prefer more advanced modules such as NodeMCU, ESP-12, or ESP32 for projects requiring more I/O capabilities. Despite its limited GPIOs, the ESP8266-01 is popular in applications such as portable electronics, robotics, home automation, and wireless data logging, where lightweight Wi-Fi connectivity is essential. Its small size, low cost, and ease of use make it a great choice for basic IoT projects requiring reliable wireless communication.
