Product description: Unit PoE-P4 - Ethernet PoE controller with ESP32-P4 and MIPI CSI/DSI - M5Stack U213
The Unit PoE-P4 is a high-performance embedded controller based on the ESP32-P4NRW32 chip with two 360 MHz RISC-V cores and an additional energy-efficient 40 MHz core. The module is equipped with 16 MB of Flash , 32 MB of PSRAM , and a 10/100 Mbps Ethernet controller with IEEE 802.3at PoE support, enabling simultaneous data and power transmission over a single Ethernet cable. The device offers MIPI DSI and MIPI CSI interfaces for displays and cameras, as well as USB Type-C Host and OTG ports, Grove, Hat2-Bus, SDIO, and ISP connectors . The built-in RGB LED , user button, and IR emitter make the module ideal for Smart Home systems, HMIs, edge computing, and IoT applications.
