Low cost remote IP KVM and control, is it possible?

Posted by jpluimers on 2021/09/20

A long time ago, I bought one [Wayback/] SpiderDuo Local and Remote KVM Over IP | Lantronix, which – without power control unit – was already some USD 400 (while writing this in fall 2021, the price has increased to almost USD 600 []).

1PORT Local + Remote USB Securelinx Spiderduo KVM Over IP : Electronics -

It was about the only “affordable” remote KVM over IPv4 available and by now has a big drawback: it’s based on Java in the browser, which is a pain in the ass to keep working.

So I went looking for alternatives and found only two reasonable ones:

I will likely go for the Pi-KVM ; it’s on kickstarter right now

Not only that, but I found a few comparisons favouring PiKVM:

I found the Pi-KVM via [] Solar Designer on Twitter: “PiKVM v3 HAT, “Raspberry Pi based open-source KVM over IP” by @mdevaev, is now funded on Kickstarter “

At USD 145 or less on kickstarter (excluding a Raspberry Pi 4 or power brick, so add some USD 50 for those), it is way cheaper than the SpiderDuo above which I bought some 5 years ago.

The kickstarter closes in about a week from now, so if you consider one: don’t be late! [Wayback/] PiKVM v3 HAT by Maxim Devaev — Kickstarter shows what you get:

  • The PiKVM v3 HAT board for Raspberry Pi 4
  • USB-C bridge board – to connect the HAT with Pi over USB-C
  • ATX controller adapter board and wiring – to connect the HAT to the motherboard (if you want to manage power supply through hardware)
  • 2 flat CSI cables
  • Screws and brass standoffs

You will also need:

  • Raspberry Pi 4 with 2Gb RAM or more
  • MicroSD card
  • USB-C to USB-A cable
  • HDMI cable
  • Straight Ethernet cable (for the ATX expansion board connection)
  • Power supply unit (5.1V 3A USB-C, recommended by the Raspberry Pi)

You can use our free 3D printing case design to build a beautiful complete unit or wait a bit for the official PiKVM metal case we are working on!
