M5Stack Unit PoE with ESP32-P4

The M5Stack Unit PoE-P4 is a powerful, compact PoE Ethernet controller based on the ESP32-P4 SoC with a RISC-V dual-core processor @ 360 MHz and a low-power core @ 40 MHz. It integrates 16 MB flash, 32 MB PSRAM as well as the IP101GRI Ethernet PHY for 10/100 Mbps communication. The PoE support according to IEEE 802.3at enables data transmission and power supply via a single Ethernet cable with up to 6 W output power.

Recommended Accessories:

• Ethernet Cable

Features:

• ESP32-P4 RISC-V dual-core @ 360 MHz with LP-core @ 40 MHz, 16 MB flash and 32 MB PSRAM for powerful edge computing and HMI applications
• IEEE 802.3at PoE support with up to 6 W output power enables power and data supply through a single Ethernet cable
• MIPI-DSI (2-lane) and MIPI-CSI (2-lane) each 24-pin FPC for display and camera integration up to 1920 × 1080 px directly on the controller
• 10/100 Mbps Ethernet via IP101GRI PHY for stable, wired network connections in industrial and IoT applications
• Two USB type-C ports (Host + OTG/Debug) as well as Grove, Hat2-Bus, SDIO and ISP for extensive peripheral expansion options
• Web interface out of the box for direct configuration of GPIO, RGB LED and buttons via the browser without firmware development

Application Examples:

• Industrial HMI terminals with PoE power, MIPI display, and camera – all via a single Ethernet cable
• Edge computing nodes for image processing, machine vision and AI inference with MIPI-CSI camera input
• Smart building gateways with wired Ethernet connection for reliable data transmission without WLAN dependency
• Network camera controller with MIPI-CSI for high-resolution image capture and local processing
• Industrial IoT controls with PoE supply for easy installation without separate power cables
