Usr Wifi232
Overview
Product sourcing insights & recommendations
The USR-WIFI232 series, manufactured by PUSR (USR IOT), is a mature line of industrial-grade serial-to-WiFi modules and converters. In the 2026 market, these products are increasingly transitioning from legacy solutions to more advanced models like the USR-W610 and W630 to meet modern industrial standards for stability and protocol support.
Key Insights
* Product Lineup: The series includes embedded TTL modules (A2/B2) for low-cost integration and industrial-cased converters (602/604/610) for RS232/RS485 bridging.
* Market Position: While highly reliable for industrial environments with its -40°C to 85°C operating range, it faces intense competition from ESP32 modules (consumer/light industrial) and High-Flying's HF-LPB100 series.
* 2026 Trends: There is a significant surge in demand for Industrial IoT (IIoT) retrofitting, where legacy serial equipment is being connected to cloud systems via these converters.
* Sourcing Status: Units are readily available from Jinan and Shenzhen suppliers, with modules priced between $6.70–$9.99 and finished industrial converters around $35–$42.
The comprehensive report below provides a deep dive into technical specifications, competitive benchmarking, and migration recommendations for modern IIoT applications.
