I am amazed that there is an ESP that can handle this and with just 32MB of RAM: https://docs.espressif.com/projects/esp-dev-kits/en/latest/e...

a 1280*720 frame, 16 bit, ping-pong buffer uses only 3.6MB of ram, still plenty of ram left for compression. The Keyboard/mouse component use like 512KB ram at most(even less, HID is cheap).

or make one yourself: https://github.com/espkvm/espkvm

Maintainer (espkvm) here. :) Thanks for the mention ;) It started as a firmware for myself: I wanted a KVM, but not a Linux system inside one. A colleague talked me into publishing it and it grew from there. It runs on ESP32-P4 dev boards, no custom hardware. I am not saying it is better than JetKVM. What I find more interesting is that the Mini landed on the same chip. Their stack is completely different from the Li…

Hi, thanks for sharing.

Have you considered using usb-hdmi capture dongle instead of using hdmi-csi. That is my idea, you bring your own capture dongle, plug it in and good to go. The esp32-s3 (and P4 i guess) support usb host, and there is uvc example from esp-idf.

Does anyone know such a device, but for a CUPS/SANE server? It would allow tou to secure a printer/scanner (which often use out-of-date software stacks). I'm currently using a RPi for this, but require partly to use qemu to run this to emulate a x86-64 binary (Brother driver). How did we end up with this mess. TVs and STBs are same story.

How old is your Brother? Mine's 8 years old and it can print/scan without needing to download any drivers (using IPP/eSCL). I was surprised when I set it up for the first time, because it took me like literally three clicks via KDE's Settings applet, never have I ever had such an easier time setting up an MFP on any OS.

The GL-iNet Commet X is a 4-port IP KVM. It does 4K, albeit at 30fps. https://nascompares.com/2026/06/26/gl-inet-comet-x-kvm-early...

I have the single port PoE version of the glinet. Its been rock solid so far. I’ve been wanting this 4 port version. But they’re sold out every time I check their site.

I got mine as a side-effect of ordering the Comet Q on Kickstarter...

There is also the Comet 5G, which gives you cellular backup. I use it to control my OpenBSD home router when traveling if my Internet connection goes down.

If you have an Intel CPU, there is a good chance you have a KVM built-in (whether you wanted one or not): Intel AMT. Its reputation was tarnished by Intel's dissimulation and opacity about the technology, and a streak of critical vulnerabilities disclosed in late 2017. I chose to take my chances with it anyway for my homelab server. It is secured with a password, mutual TLS (client has to provide a cert), and restric…

I've had a number of thinkpads and nucs with vpro/amt. All the things you say are technically correct, in practice the software and feature set are horribly documented. I've spent numerous hours trying to get it to work reliably only to find out something is too old or not supported or just disabled.

The phsyical kvms just work and worth the $.
