Waveshare ESP32-P4-WIFI6

ESP-KVM is free, open-source firmware that turns the Waveshare ESP32-P4-WIFI6 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 PoE board without the wired port. Capture and USB confirmed; Wi-Fi is the only way in.

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	71 x 21 mm
Network	Wi-Fi 6 (ESP32-C6) only
Capture connector	15-pin Raspberry Pi camera connector
microSD	yes
To the target	USB OTG on an MX1.25 4-pin header

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.

Contributed by @nwomn, who has one: capture through the C790 and the USB keyboard and mouse both work, and the expansion header is checked against the board.

Wiring

USB OTG is on an MX1.25 4-pin header, so the target needs an MX1.25 to USB-A cable.

Wi-Fi

Wi-Fi is the only link it has, and it used to stall: the board pulls its SDIO lines up through 51k where Espressif ask for 10k, which lost the co-processor's data-ready interrupt. Since 0.41.1 the chip's own pull-ups are on for this board, and it holds. That is one board and one tester - #27 if yours differs.
