P4M-440G Serial MQTT Ethernet Module by Sollae Systems

MQTT (Message Queuing Telemetry Transport) is a publish-subscribe messaging protocol that operates on top of the TCP/IP protocol. This protocol comprises a server and a client, with the server serving as an MQTT broker and the client functioning as a publisher or subscriber. The P4M-440G from Sollae Systems serves as an MQTT client module, capable of receiving AT commands via the UART port and offering diverse MQTT communication functionalities. Using the P4M-440G module users can easily implement MQTT functions on their MCU or microcomputer.
