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 serves as an MQTT client module, capable of receiving AT commands via the UART port and offering diverse MQTT communication functionalities. Consequently, users can easily implement MQTT functions on their MCU or microcomputer using this module.

  • MQTT Client Functionality
  • Simple AT Command Control Method Supported
  • Equipped with 1 x 10/100Mbit Ethernet Port
  • 1 x UART Port (default 19200 bps)
  • Supports Security Protocol (TLS v1.2)
  • Storage of Root CA and Client Certificates: Integration with commercial clouds (AWS & AZURE)
  • Supports USB-Type PC Connection
  • Dedicated Configuration Program: PHPoC Debugger
