TESIGN TAKE

It earns its keep exactly where remote desktop dies, and fills that gap with $40 of parts and a browser flasher — but take the author's 'do not put this on the public internet' literally.

A summary, not legal advice.

WHY IT MATTERS

Remote desktop needs a running OS; this board plugs into the target's HDMI output and a USB port and shows the BIOS, boot menu or a machine with no OS at all in a browser. It is built from an ESP32-P4 board and a Toshiba TC358743 HDMI-to-CSI bridge (Geekworm C790), and the homepage puts the parts at about $40. Measured at 1080p: MJPEG 20 fps on the Waveshare ESP32-P4-ETH, H.264 22–24 fps on the Function EV (rev 3.2). Virtual-media boot, Wake-on-LAN, ATX power control, Home Assistant over MQTT and WireGuard/Tailscale are included; it flashes from the browser, latest release v0.48.0 (2026-09-14).

BUILD FROM THIS

  • Fit one to each homelab server or mini-PC as a stand-in for a BMC, or combine runbooks (a macro that waits for 'Press F2' on screen, then presses F2) with the cron scheduler for text-screen jobs such as BIOS setup and boot menus, and for overnight checks.

WHO IT'S FOR

Homelab and mini-PC owners
enter the BIOS and reinstall an OS remotely
Home Assistant users
MQTT auto-discovery exposes a screen still, power buttons and sensors
Embedded developers working with the ESP32-P4 or HDMI capture
TC358743 bring-up and CSI register code to study

START IN 5 MINUTES

# 1. Download your board's espkvm-<version>-<board>-merged.bin from Releases (e.g. -p4-eth-, -funcev-)
# esptool --chip esp32p4 -b 921600 write-flash 0x0 espkvm-<version>-<board>-merged.bin
# # or flash straight from Chrome/Edge at https://espkvm.io/flash/
# 2. Connect Ethernet, HDMI from the target and the board's USB 2.0 OTG-HS port to the target, then open https://espkvm.local/
# 3. Sign in as admin / admin → the console will not continue until the password is changed

CAVEATS

  • Apache-2.0; the author notes H.264 is patent-encumbered whatever licence the code carries
  • Hardware: an ESP32-P4 board with 32 MB PSRAM and 16 MB flash plus a TC358743 capture board (Geekworm C790) — about $40 per the homepage; chip revision (below/above 3.0) changes the build
  • No security review yet, so keep it off the public internet (VPN built in); HDMI audio not implemented; H.264, keyboard and mouse need HTTPS with the device CA trusted
