MQTT Unit is an Ethernet communication module specifically designed for MQTT (Message Queuing Telemetry Transport) communication. It features an embedded W5500 Ethernet chip, which enables seamless connectivity to Ethernet networks. The module also includes a UART communication interface, allowing for control via AT commands. In addition, it integrates an RJ45 adaptive 10/100M network port for easy network connectivity.
One of the notable features of MQTT Unit is its support for 4 Topics subscription. This means that it can simultaneously subscribe to and handle data from up to 4 MQTT topics. This capability, combined with its low network latency, makes it well-suited for applications requiring real-time or near-real-time data communication.
The MQTT Unit finds extensive use in a variety of industrial automation, security monitoring systems, automatic measurement and control systems, and equipment data integration with cloud platforms. Its reliable and efficient MQTT communication capabilities make it an essential component in these applications, facilitating seamless data transfer and integration with cloud-based system

LEARN AND DOCUMENTS
The M5Stack MQTT unit processes MQTT messages via Ethernet, which are controlled by a microcontroller via a UART interface. Microcontrollers without Ethernet / WiFi can use this module to establish MQTT connections.
