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 WT99P461-S1 yet, and one request from someone who has it is enough to make one. What it does → Try the demo →

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: 15-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 WT99P461-S1 is a large development board built on the WT01P461-S1 module, an ESP32-P4 rev 3.2 with 32 MB of PSRAM and an ESP32-C61. It has 100M Ethernet through an IP101, RS-485, CAN, audio and a microSD slot.

The camera connector J15 is a 15-pin 1.0 mm one, and the schematic shows the Raspberry Pi order: lanes and clock on pins 2 to 9, CAM_IO0 and CAM_IO1 on 11 and 12, I2C on 13 and 14, 3.3 V on 15. Ethernet gives the network, so the C61 is not needed. It talks SPI, which ESP-KVM does not support yet.

The high-speed USB goes to the USB-A socket J4. A load switch always drives 5 V onto its VBUS, as on the Waveshare NANO. So the lead to the target would be an A-to-A cable with the 5 V wire cut. The USB-C socket J3 is only full speed, and J1 is a USB-UART bridge for flashing. The microSD slot sits on SDMMC slot 1 behind an analog switch on GPIO 33. A port would need the Ethernet PHY pins, the camera I2C pins and that switch.

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.
