Waveshare ESP32-P4-WIFI6-POE-ETH

ESP-KVM is free, open-source firmware that turns the Waveshare ESP32-P4-WIFI6-POE-ETH into an IP-KVM: the screen, keyboard and mouse of another computer in your browser, from the BIOS up. Add an HDMI capture board, flash it from the browser, and it runs with no Linux, no app and no cloud. What it does → Try the demo →

The first supported board that takes PoE: one cable to a KVM in a rack. 1080p H.264 at 23 fps.

Status	Run on hardware
Family	All Waveshare parts
Chip	ESP32-P4, rev 1.x or rev 3.x (an image for each)
Memory	32 MB PSRAM, 32 MB flash
Size	68 x 55 mm
Network	100M Ethernet with PoE, Wi-Fi 6 (ESP32-C6)
To the target	USB-A
Capture connector	15-pin Raspberry Pi camera connector
microSD	yes
Measured	1080p H.264 at 23 fps (rev 3.x)

Which revision? Read the chip: ESP32-P4NRW32X, with an X at the end, is rev 3.x; ESP32-P4NRW32 without it is rev 1.x. The product code does not tell. Or plug the board in and read it in the browser: it shows the revision, the flash and the PSRAM.

One cable to a KVM in a rack instead of two. The same IP101 Ethernet, microSD wiring and ESP32-C6 as the other Waveshare boards, and a full-size USB-A port for the target.

Confirmed by @deltorek112 on rev 3.x silicon with the p4-poe-rev3 image, through Waveshare's HDMI to CSI adapter: 1080p over H.264 at 23 fps (#51).

Waveshare said in August 2026 that these ship rev 1.3, but the one tested was rev 3.x. Check the boot log before flashing: it prints chip revision:. The pre-3.0 image has not been run on this board yet.

Its 40-pin header has the Raspberry Pi layout, with the capture chip's I2C bus on pins 3 and 5, so a "DS3231 for Pi" clock module should plug straight onto pins 1-9 (read from the vendor pinout, not tried on this board).
