Unit MQTT
Description
Unit MQTT is an Ethernet MQTT communication module with an embedded W5500 Ethernet chip. It uses a UART communication interface (controlled by AT commands) and integrates an RJ45 adaptive 10/100M Ethernet port. It supports 4x Topic subscriptions. With extremely low network latency and high stability, it is suitable for various industrial automation, security monitoring systems, automatic measurement and control systems, and device data cloud applications.
