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 →

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.

Wiring

  • The OTG port is a USB-A socket that drives its own 5 V.
  • So the lead to the target is an A-to-A cable with the 5 V wire cut. A plain A-to-A cable joins two 5 V supplies.

It ships as either chip revision under one product code; check Chip rev: in the boot log and pick the image to match.
