The Pi-Cast KVM is a compact, open-source KVM (Keyboard, Video, Mouse) over IP device based on the Raspberry Pi CM4. It is powered by PiKVM, an open-source IP-KVM solution, and allows you to control and manage other devices remotely regardless of the operating system or even if one isn’t installed.
The Pi-Cast KVM is capable of controlling any device with HDMI and USB ports. It works for low-level access and enables BIOS and UEFI configuration without an operating system installed. You can turn off and start the target system, as well as check for low-level hardware problems, all from a web browser.
The Pi-Cast KVM is similar to the PiKVM v3 but is built around the Raspberry Pi CM4 (like the PiKVM v4) instead of being a HAT for Raspberry Pi SBC. The company behind this device has compared the Pi-Cast with market alternatives such as PiKVM v4 Plus and the BliKVM HAT.
Pi-Cast comes in five different versions. Besides the base model, three upgraded versions feature one of three expansion modules, the Ethernet/ATX/Console HAT, the USB 3.0 & M.2 B-key module, or the dual-ATX multiport switch, in a custom enclosure that includes the Pi-Cast KVM board. Additionally, two other models add USB 3.0 & M.2 B-key functionality to the Ethernet/ATX/Console and dual-ATX variants.
Pi-Cast KVM base model specifications:
- Support Board: CM4 (and 4B or Zero 2W with adapter)

- Weight – TBD

The hardware schematics and software for the Pi-Cast will be completely open-source. The GitHub repository is currently empty, but the makers say it will be updated once the campaign has reached its funding goal.
At 86 x 56 x 15 mm, the Pi-Cast is currently the smallest PiKVM-based device. The base model is priced at $199 with free worldwide shipping. It comes pre-assembled with a Compute Module 4, heat sink, fan, and enclosure, and includes a USB 3.0 Type-C cable, a USB Type-A to Type-C cable, and an HDMI cable. Pricing information for all the other Pi-Cast products can be found on the Crowd Supply page. Funding is set to end on February 8, 2024, and orders are expected to ship on June 24, 2024.
