Universal ESP32 IoT Controller with PoE Ethernet, RS485, and I²C
SKU: MD43002
The ESP32-PoE IoT Controller is a universal, highly functional control module designed for reliable Internet of Things (IoT) applications, building automation systems, and industrial installations.
The heart of the device is the proven, dual-core ESP32 microcontroller (XTensa LX6 processor clocked up to 240 MHz), combining high performance with excellent software ecosystem support. The module offers full wireless connectivity supporting Wi-Fi 2.4 GHz (802.11 b/g/n) and Bluetooth 4.2 (LE), allowing for convenient wireless management and cloud integration.
The key feature of the MD43002 is its integrated wired 10/100 Mbps Ethernet interface with a standard RJ45 connector and full PoE (Power over Ethernet) support. This enables simultaneous data transmission and power supply to the device via a single network cable (UTP twisted pair), radically simplifying installation in locations with limited access to the power grid.
For maximum flexibility, the module is equipped with a rich set of wired and control interfaces: an industrial RS485 bus, a Qwire I2C connector for quick sensor attachment, a USB (UART) port for programming and diagnostics, and 4 universal control outputs. In addition to PoE power, the device features a traditional, wide-range power supply system accepting 7…32 VDC, making it a complete, robust, and deployment-ready IoT solution.
