Product description: MQTT PoE - MQTT Ethernet communication module with PoE port - W5500 - Unit extension module for M5Stack development modules
Another Unit type extension designed for M5Stack development modules. MQTT PoE is an Ethernet MQTT communication module, additionally equipped with port enabling power supply via PoE (with 1.2 A load capability at 5 V / 6 W). Based on Ethernet W5500 chip. It uses UART protocol to communicate with connected modules, and can be programmed via AT command lines. The module is also equipped with an integrated RJ45 10 / 100 Mbps network port. It supports subscription of four topics (topic) and is used in widely understood industrial automation, security monitoring systems or automatic measuring systems.
Set contents
- MQTT PoE - MQTT Ethernet communication module with PoE port - W5500 - Expansion Unit for M5Stack development modules
- Connection cable terminated with Grove connector - length 20 cm
The set also includes a connection cable with a length of 20 cm.
In the upper part of the module are written sample lines of AT commands.
Features
- Equipped with high quality W5500 chip and ARM Cortex-M3 processor
- Equipped with RJ45 10 / 100 Mbps network port
- PoE power supply
- Ethernet MQTT communication
- Programmable via AT command line (default) or via UIFlow or Arduino programming platform
- The manufacturer has placed sample AT commands on the casing, making it easier to use the extension for less advanced users
What is MQTT?
MQTT - MQ Telemetry Transport. It defines an extremely simple data transmission protocol. It is currently the easiest and most popular way to send data to the cloud. Data published using the MQTT protocol is in text form. This means that you can convert the data structure to JSON format (or any other arbitrary text format) and then publish it without much trouble. The MQTT protocol is dedicated to transmission for devices that do not require high bandwidth. By limiting the transmission rate, the protocol provides greater reliability.
In the user's guide prepared by the manufacturer you can find sample program codes and a set of AT commands. Check it out!
