ESP-KVM is free, open-source firmware that turns an ESP32-P4 board into an IP-KVM: another computer's screen, keyboard and mouse in your browser, from the BIOS up, with no Linux and no cloud. There is no ESP-KVM image for the Wireless-Tag WTDKP4C5-S1 yet, and one request from someone who has it is enough to make one. What it does → Try the demo →

Wireless-Tag WTDKP4C5-S1

A small ESP32-P4 development board on the WT01P4C5-S1 module, which has an ESP32-C5 for dual-band Wi-Fi.

StatusNot supported yet: no ESP-KVM image for it. It looks like it should work.

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.

What ESP-KVM needs from a board

  • ✓ 32 MB of PSRAM. It has the 32 MB of PSRAM the video needs.
  • ✓ A camera connector the capture board fits. The HDMI capture board's Raspberry Pi camera ribbon fits its camera connector. Connector: 22-pin, Pi order.
  • ✓ High-speed USB towards the target. Its high-speed USB comes out where it can face the target as a device.
  • ✓ A network. It has a network: Ethernet, or Wi-Fi through a co-processor.

Read from the maker’s documents, checked 2026-11, not from a board in hand.

The WTDKP4C5-S1 is a small board around the WT01P4C5-S1 module. The module holds both the ESP32-P4 and an ESP32-C5, linked over SDIO, so Wi-Fi works on 2.4 and 5 GHz. It takes power from USB-C or a 12 V jack.

The camera connector J4 is a 22-pin 0.5 mm one, and the schematic shows the Raspberry Pi 22-pin order. The high-speed USB goes to USB-C J1, which the guide says can work as a USB device. Both fit ESP-KVM.

The module is made with 16 or 32 MB of PSRAM, and ESP-KVM needs the 32 MB one. Wireless-Tag's example also names two versions, N16R32 and N16R32X, so the P4 can be rev 1.x or rev 3.x, and the marking tells which. There is no microSD slot, so virtual media and recordings would have nowhere to go. There is no Ethernet on the board. The header brings out the P4's EMAC pins for an external PHY. A port would need the camera I2C and enable pins and the C5's SDIO pins.

Have one?

One request is enough: I add a board as soon as someone who has it can try a test build.

  1. Open a board request in Discussions. The form asks for the board's shop page, its schematic if there is a link, the chip marking and the capture board you have.
  2. I make a test image from the schematic and post it in the thread.
  3. You flash it on the flasher with Install another version from a file, and tell me what works. The flasher's Back up the flash keeps the board's old firmware.
  4. Once the picture, the keyboard and the network work, the board goes into the catalog with its own image and updates.
