Product Description

The USR-WIFI232-B2 is a compact Serial to WiFi module designed for IoT wireless communication, integrating 1 serial port (UART) and supporting TCP/IP protocols for seamless data transmission. It operates within a 3.3V-5V DC range and features an industrial-grade temperature tolerance (-40°C to +85°C), making it suitable for harsh environments in sectors like industrial automation, smart energy, and remote monitoring. With built-in 802.11 b/g/n WiFi compatibility, the module enables wireless connectivity up to 100 meters (open space) and supports AP/STA modes for flexible network configurations. Its low-power design (typical 120mA@5V) and firmware customization options enhance adaptability, though external antennas may be required for extended coverage. The USR-WIFI232-B2 excels in reliability and rapid deployment for M2M applications.
