Introduction

This module is an all-in-one 802.11b/g/n Wi-Fi module that provides a solution for connecting users' physical devices to Wi-Fi wireless networks and transferring data via interfaces such as UART. With this module, conventional low-end serial devices or MCU-controlled devices can easily connect to Wi-Fi wireless networks, enabling IoT-based control and management. The module hardware integrates a MAC, baseband chip, RF transceiver unit, and power amplifier; the embedded firmware supports Wi-Fi protocols and configuration, as well as the TCP/IP protocol stack for networking. The module is professionally optimized for applications in low-traffic, low-frequency data transmission fields such as smart home, smart grid, handheld devices, personal medical, and industrial control.
