ESP8266 WiFi ESP-01 Module

The ESP8266 WiFi ESP-01 Module is one of the most compact and widely-used WiFi transceivers for IoT and DIY electronics. Built on the reliable ESP8266EX chipset, the ESP-01 provides stable and efficient wireless communication capabilities while keeping a small footprint. This module is especially popular in scenarios where space and power constraints are critical.

Despite its size, the ESP-01 supports 802.11 b/g/n WiFi protocols, has an integrated TCP/IP stack, and includes 2 GPIO pins for connecting peripherals. It operates at 3.3V, communicates via UART, and is perfect for adding WiFi capabilities to Arduino, ATmega, and other microcontroller platforms. It can function as a standalone microcontroller or as a WiFi adapter for existing MCU boards.

Thanks to its simplicity and cost-effectiveness, the ESP-01 is a go-to module for WiFi-enabled smart gadgets, IoT sensors, remote controls, and automation systems.
