Introduction

The USR-WIFI232-B2 module is an integrated 802.11b/g/n Wi-Fi module that provides a solution for connecting users' physical devices to a Wi-Fi wireless network and transmitting data via interfaces such as UART. Through the USR-WIFI232-B2 module, traditional low-end serial devices or MCU-controlled devices can easily connect to a Wi-Fi wireless network, enabling IoT control and management. The module integrates MAC, baseband chip, RF transceiver unit, and power amplifier at the hardware level; the embedded firmware supports Wi-Fi protocol and configuration, as well as the TCP/IP protocol stack for networking. Professionally optimized for low-traffic, low-frequency data transmission applications such as smart grid, handheld devices, personal medical, and industrial control.
