Description
Unit PoE‑P4 is a high‑performance PoE Ethernet embedded controller powered by the ESP32‑P4 SoC (RISC‑V 32‑bit dual‑core @ 360MHz + LP single‑core @ 40MHz). It integrates 16MB Flash and 32MB PSRAM, and features the built‑in IP101GRI Ethernet PHY supporting 10/100 Mbps communication. The device also supports PoE power delivery with a maximum output of 6W, and includes an onboard DC‑DC converter to supply system power, greatly simplifying power wiring in practical applications.
It is equipped with a 24P FPC display expansion interface (MIPI DSI + TP + BL) and a 24P FPC camera interface (MIPI CSI), supporting high‑resolution display output and image capture. For peripheral expansion, it provides one USB Type‑C Host (USB 2.0) port for connecting U disks, HID devices, and other peripherals, plus one USB Type‑C (USB 2.0) port supporting OTG and firmware download for debugging. In addition, it features a Hat expansion interface, SDIO & ISP IO expansion interfaces, and a Grove interface, enabling flexible connection to a wide range of sensors and peripherals.
The device also integrates an RGB indicator LED, an infrared transmitter circuit, and a user button to support status indication, local interaction, and infrared signal transmission. It is ideal for applications such as industrial HMI, PoE smart terminals, vision acquisition nodes, smart home controllers, and edge computing devices.
