Pi-KVM - Open and cheap DIY IP-KVM on Raspberry Pi
|Great project review by Novaspirit Tech: YouTube
Boring technical details from us: YouTube
And here some examples from us and our happy users.
|Easy and powerful||The widest hardware support||Production features|
|Just a few cheap parts and half an hour of assembly and you will have the device that supports Full HD video, Mass Storage Drive, keyboard & mouse, control the ATX power and much more.||There are many ways to build a Pi-KVM. Raspberry Pi models 2, 3, 4, or ZeroW may be used. Video capture devices can be attached using the CSI-2 or USB interfaces.||Access via Web UI and VNC, IPMI BMC/SoL and Redfish support, Wake-on-LAN server, advanced authorization and SSL encryption. This is just a short list of what Pi-KVM can do out of the box.|
DIY Getting Started
We are also currently developing our own
HAT for the Raspberry Pi 4.
Watch the video!
This device will have all the features of the DIY version, including:
Subscribe for Pre-order
... and we'll let you know when you can purchase the board.
Status as of April 2021: We expect to receive the first batch from the factory on April 20. Hurray! Sales are expected to start shortly afterwards.
Pi-KVM's development is made possible only through
the financial support of its awesome sponsors :)
Fully-featured and modern IP-KVM
- Easy to build
A ready-to-use OS images and friendly build environment. The hardware can be made in half an hour and without soldering.
- Very low video latency
~100 milliseconds of video latency. This is the smallest delay of all existing solutions.
- Extra lightweight Web UI and VNC
No weird proprietary clients. No ugly applets. Just use your favorite browser to connect to the Pi-KVM. No flash plugins either! Ah, and VNC is also supported.
- Keyboard & mouse
Mouse usage works directly in the browser. The keyboard emulator supports displaying the state of the keyboard LEDs.
- Mass Storage Drive
On the Raspberry Pi 4 and ZeroW, Pi-KVM can emulate a virtual CD-ROM or Flash Drive. A live image can be uploaded to boot the attached server.
- ATX power management
With a very simple circuit that can be assembled on a breadboard, the power button of the attached server can be controlled using the ATX button headers on the motherboard.
Pi-KVM can be opened to the Internet and no one will get access without the authorization. SSL encryption is used to protect traffic from being intercepted by third parties.
- Local monitoring
Pi-KVM monitors the health of the Raspberry Pi board and will warn you if it's too hot or is not receiving enough power.
- GPIO management
You can control GPIO and USB relays via the web interface. The extensible interface allows you to make anything out of it.
- Linux-based embedded OS
The Pi-KVM OS is based on Arch Linux ARM and can be customized for any needs. Thousands of pre-built binary packages are at your service and can be updated with a single command!
- Read-only filesystem
By default the OS runs in read-only mode, as an embedded system should. This prevents damage to the memory card due to a sudden power outage.
- VNC server
The managed server and its BIOS can be accessed using a regular VNC client which supports JPEG compression.
- IPMI BMC/SoL and Redfish
Use ipmitool, ipmiutil or any existing network infrastructure that supports IPMI to manage the server's power and access to serial port via LAN. Redfish and redfishtool supported too.
Pi-KVM can be configured to power up a managed server using WoL. This will be available in the Web menu.
- Extensible authorization methods
Multiple Pi-KVMs can be configured to use a common authorization service. PAM and its rich authorization mechanisms can also be used to integrate Pi-KVM into your existing authentication infrastructure.
- Macro scripts
If repetitive actions must be performed on the attached server (or on several different servers), a macro can be recorded with keyboard & mouse actions and can be played back mutiple times.
- Open & free
Pi-KVM is Free and Open Source Software released under the GPLv3.
- Community & support
Pi-KVM has a large community. Join the Discord chat if you have any questions.
Pi-KVM was designed as a set of microservices with a plug-in architecture. It's very easy to modify and maintain.
- Comprehensive API
Everything that can be done via the user interface can also be done via a powerful HTTP API.
We created our very own MJPG video server written in C with multi-threading support and GPU video encoding - the fastest streaming solution available to provide the best video quality for Pi-KVM. We also tested a lot of hardware configurations so that you can be sure devices you assemble will work reliably.
