Onchdbfhuu HY2.0-4P Unit ChainBus Communication Protocol Conversion Module Multi-Function Expansion Interface for Expand Chain Devices

The ChainBus's top multi-functional expansion interface can be used to expand Unit series devices, supporting communication control, GPIO management input/output, ADC acquisition, and NVIC interrupt management. It supports multiple protocol interface conversions, and the same bus can be expanded to connect various peripherals. It also integrates hardware control and data interaction capabilities. Unit ChainBus is a Chain series communication protocol conversion unit. The device integrates an STM32G031G8U6 chip and uses the UART serial cascading communication protocol to achieve multi-device chain connection. The ChainBus features UART interfaces on both sides for connecting Chain series devices, supporting functions such as device UID lookup, version lookup, link device enumeration, and heartbeat communication. It is suitable for industrial control, IoT, home, and other fields, providing an effective solution for unified management and data interaction of multiple devices.
