The M5Stack Unit PoE-P4 is a compact development kit powered by PoE, featuring the ESP32-P4NRW32 SoC. It comes with a 10/100Mbps Ethernet PHY, enabling IEEE 802.3at PoE for power and data transmission through a single cable and supports MIPI DSI/CSI display and camera interfaces.
This device is intended as a network-enabled node with built-in PoE (up to 6W), a USB Type-C host port, a separate USB Type-C OTG/download interface, an RGB LED, IR transmitter, user button, Grove (HY2.0-4P) port, Hat expansion header, and SDIO/ISP expansion interfaces, making it apt for industrial HMI panels, PoE smart terminals, camera/vision acquisition nodes, smart home controllers, and edge computing devices.
