Features: The USB to MBUS Slave Module features integrated FC722 chip for low bus leakage current and full signals isolation, ensuring safe communication between MBUS devices and computer USB ports without risk of voltages damage. Compliant with M BUS international standards, this module offer adjustable bus voltages (12V-42V), continuous bus current (200uA 3mA), enhanced 5V/3.3V regulated output, and stable UART communication at 300 9600 bauds rates. for engineers and developers working on industrial automation, smart metering systems, or embedded device prototyping requiring MBUS slave connectivity. for laboratory testing, field installations, and maintenance scenarios where USB to MBUS communication bridges are needed to debug meter networks or sensorings clusters. Its selfs powered signals circuit draws energy directly from the bus, eliminating USB dependency while maintaining high stability across temperature variations and electrical interferences.
