Geekworm KVM-A8 PCIe KVM Over IP Kit for Raspberry Pi 4 - Remote PC

In this review the Geekworm KVM-A8 PCIe kit is examined as a DIY solution for adding full KVM over IP control to a desktop or server using a Raspberry Pi 4 Model B. The kit is clearly aimed at experienced builders and system admins who want remote power control, BIOS-level access and virtual media without buying a commercial appliance. Its biggest selling point is the combination of keyboard/mouse/video redirection plus remote power and virtual CD/USB functionality delivered through a Raspberry Pi 4, making it a flexible low-cost alternative for lab, rack or home server setups.

Key Features

• KVM over IP: Provides browser-based keyboard, mouse and video redirection so users can operate a remote machine as if seated at its console.
• Virtual media support: Lets operators reinstall or image an OS using a Virtual CD-ROM or Flash Drive from the remote session, simplifying maintenance and recovery tasks.
• Remote power control: Enables remote turn on, turn off and restart of the host computer for out-of-band management and power cycling.
• Raspberry Pi 4 compatibility: Designed for Raspberry Pi 4 Model B boards (1GB/2GB/4GB/8GB) so users can reuse an existing Pi 4 as the KVM controller.
• PoE or USB-C power: Supports Power over Ethernet for clean installs in racks or a 5.1Vdc +/-5% 3A USB-C input when PoE is unavailable, allowing flexible power options.

Who It's For

This product is for professional users, system integrators and hobbyists comfortable with assembly, wiring and software configuration. It is ideal for lab and rack environments where remote BIOS access, OS reinstall capability and power control are required without a full commercial IP KVM appliance.

It is not suitable for novice users or those who expect a plug-and-play network appliance; the kit ships unassembled and requires a Raspberry Pi 4 Model B (not included), basic soldering or connector work and familiarity with the Geekworm Wiki for software setup. It also does not support Raspberry Pi 3 or Pi 5.

Pros & Cons

Pros

• Compact PCIe form factor that fits into empty expansion slots for a tidy install and good mechanical fit.
• Rich remote functionality including virtual media and BIOS-level access, useful for recovery and maintenance.
• Good build quality and straightforward assembly for users who are comfortable with hardware projects.
• PoE support allows neat installations in networked racks without extra power wiring.

Cons

• Unassembled and labeled for professional users only, so it requires technical skill and time to install and configure.
• Some customers reported non-standard pinouts and mixed wiring experiences, which can complicate installation for those unfamiliar with custom connectors.
