UNIT MQTT is an Ethernet MQTT communication module with embedded W5500 Ethernet chip, UART communication interface (AT command control) and integrated RJ45 adaptive 10/100M network port. It also supports 4 Topics subscription with extremely low network latency, and is widely used in various industrial automation, security monitoring systems, automatic measurement and control systems, and equipment data on the cloud.

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.
