ESP-KVM is free, open-source firmware that turns the Waveshare ESP32-P4-NANO 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 →
Small, with Ethernet and an ESP32-C6. Capture, USB and Ethernet confirmed on both chip revisions.

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.
The same IP101 Ethernet and onboard ESP32-C6 as the bigger Waveshare boards. Contributors confirmed capture, USB and Ethernet on both silicon revisions, and Wi-Fi on rev 3.1.
It ships as either chip revision under one product code; check chip revision: in the boot log and pick the image to match.
