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 WT32P4C5-43S is a 4.3" touch screen in a plastic case. The board behind the screen is the ZX4D30CE40S-V13. It carries the WT0132P4-A1-N16R32X module, which is an ESP32-P4 rev 3.x with 32 MB of PSRAM, and an ESP32-C5 module for dual-band Wi-Fi.
What ESP-KVM needs is there. The camera connector J2 is a 15-pin 1.0 mm one in Raspberry Pi order. The high-speed USB goes to its own USB-C socket J5, which has the 5.1k CC resistors of a USB device port. The second USB-C socket, J10, is the full-speed port on GPIO 24 and 25. There is a microSD slot.
A port would need the Wi-Fi pins and the camera pins. The C5 talks SDIO on GPIO 28 to 34, with its enable on GPIO 28. The camera's I2C is shared with the touch panel on GPIO 14 (SDA) and GPIO 15 (SCL). The camera enable line has a 10k pull-up, and the schematic does not show it on a GPIO. ESP-KVM would not use the screen at first. There is no Ethernet.
Have one?
One request is enough: I add a board as soon as someone who has it can try a test build.
- 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.
- I make a test image from the schematic and post it in the thread.
- 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.
- Once the picture, the keyboard and the network work, the board goes into the catalog with its own image and updates.
