The E103-W01 Ebyte 2.4GHz Serial UART WiFi 100mW Embedded PCB Antenna ESP8266 Wireless Module is an industrial-grade Wi-Fi module based on the ESP8266EX chip, designed with a compact size, low power consumption, and multifunctionality, making it suitable for a wide range of embedded applications. It supports transparent serial transmission, Wi-Fi protocol connection, and multiple operating modes, enabling wireless communication between various devices.

The module operates with simplicity: it automatically connects to a Wi-Fi network at power-on and uses TCP Server or TCP Client protocols to exchange data. Configuration of the module is done via AT commands, and it supports SmartConfig for quick Wi-Fi network setup. Additionally, the module supports Airkiss configuration protocol, allowing for easy network setup via WeChat.

The module not only supports transparent transmission but also supports multiple communication protocols, including TCP and UDP, allowing for flexible data transmission and remote control. It can connect with up to 5 remote devices, providing strong networking capabilities. The module also features a built-in watchdog timer to ensure reliable long-term operation without crashes.

Furthermore, the module supports multiple power-saving modes, including Active Mode (for maximum performance), Low Power Deep Sleep (LPDS) Mode, Sleep Mode, and Hibernate Mode, allowing users to choose the most suitable power consumption profile depending on their needs.

This module is versatile and robust, making it an ideal choice for IoT, smart metering, and remote monitoring applications. Its ability to operate reliably in extreme temperatures (-40°C to +85°C) further enhances its suitability for industrial-grade applications.
