I couldn’t do my job without this. - PiKVM

Product reviewed: PiKVM V3 (Raspberry Pi + KVM-over-IP “hat”)

What it does (key value)

• Enables remote power on/off and control of a headless PC using HDMI video + USB keyboard/mouse from anywhere.
• Lets you view and interact with the target system, including Windows and BIOS.
• Supports “serious work” use cases such as powering on a PC over 5G while not locally connected, then interacting remotely.
• Can perform remote overclocking (implied by the ability to control the system through BIOS/OS).

Main features highlighted

Video and control over IP

• Target practical maximum: ~1080p 60.
• Reported latency: described as feeling like cursor skipping, but overall said to align with the maker’s claim of ~100 ms (best-case) before adding network latency.
• Adjustable video settings:
  • Limit frame rate
  • Choose an H.264 bitrate in the system menu to tune bandwidth usage
• Not recommended for games due to latency and bandwidth limits.

No host-PC networking required

• The host PC stays “out of the loop.”
• PiKVM connects using only HDMI + USB to the motherboard—no special host networking needed.

USB versatility

• USB isn’t limited to keyboard/mouse:
  • USB network bridge
  • Serial port support (via converters)
  • USB drive functionality for mounting disk images (ISOs)
• Remote OS installation workflow:
  • Upload an ISO
  • Initiate the chosen mode to install remotely
• Remote recovery/diagnosis support:
  • Can download images from the internet if provided an address

ATX power control and front-panel controls

• With an optional ATX adapter/breakout, PiKVM can provide:
  • Power/reset control
  • Boot sequence visibility inside the browser

Tailscale VPN support

• Can be configured with Tailscale (free personal plan) to avoid networking issues like static IPs and port forwarding.

Hardware and networking approach

• Uses a Raspberry Pi 4 with a specialized hat.
• Provides three total RJ45 jacks:
  • One for the Pi’s own LAN (Ethernet)
  • Two additional “special” ports:
    • One for serial-over-converter use cases
    • One for the ATX adapter (breaks out front-panel connectors rather than functioning as true Ethernet)

Setup and user experience

Initial setup requirements

• Flash the microSD with an image using Pi Imager (or similar).
• Power on and connect PiKVM to the network.

Finding the IP address

• If purchased as a kit, the built-in OLED display can show it.
• Otherwise:
  • Check router DHCP assignments, or
  • Use a command to list devices by MAC address patterns

Administration

• Must change the default admin password.
• Web UI includes a “KVM” menu with an interface compared to IPMI-style management.

Performance notes

• Latency is described as surprisingly good for remote KVM.
• Still not suitable for interactive gaming.

Pricing and value comparison

• Hat-only option: $160
• Full assembled kit (case + cooler + OLED + 2GB Pi 4 + 32GB pre-imaged SD): $250
• Video claims it feels like a strong value compared to:
  • Big commercial server KVMs: $500–$1000

Comparison: Tiny Pilot Voyager 2

• Price mentioned: $360
• Similar Pi-based concept but packaged more like a polished commercial product.
• Reviewer notes the Tiny Pilot claims a superior support system for IT managers/server racks (not directly tested).
• Community note: Discord may be strong, but can be worse for searchability.

Pros mentioned

• Enables remote power, BIOS, and OS interaction without touching the PC.
• Strong latency for the category (around the claimed ~100 ms best-case; emphasized as practically usable).
• Bandwidth control via frame rate and H.264 bitrate tuning.
• No special host networking required (only HDMI/USB).
• Useful for remote troubleshooting and helping less technical people (with a privacy caveat).
• Optional ATX integration for clean power/reset control and boot visibility.
• Tailscale reduces networking friction.

Cons and limitations mentioned

• Not for gaming (latency + bandwidth constraints).
• Wi‑Fi signal strength may be weak due to a steel chassis (Ethernet recommended).
• DIY/builds are less polished unless buying the full kit/options.
• Possible privacy concerns if multiple people are granted access (mitigation suggested: keep it disconnected until needed).
• Requires some network setup steps (IP discovery and password changes).

Verdict / recommendation (concise)

• The reviewer recommends PiKVM V3 as an excellent middle-ground: feature-rich enough for practical remote server/PC management, with pricing far below traditional commercial KVMs.
• Best for IT/tech users who want remote power + KVM.
• Not intended for gaming.

Unique points mentioned (all)

1. Used during being stuck in a hotel; could remote-work from hotel.
2. Remote power-on over 5G.
3. Can view/operate Windows and BIOS remotely.
4. Remote overclocking possible.
5. Claimed KVM latency: ~100 ms best-case; cursor skips but remains usable.
6. Practical video ceiling: 1080p 60 max.
7. Adjustable frame rate + H.264 bitrate to manage bandwidth.
8. Host PC needs only HDMI + USB (no host networking).
9. Supports an HDMI splitter example to integrate unnoticed.
10. USB can act as network bridge, serial, and USB drive for ISO mounting.
11. Can remotely install OS by uploading ISO and connecting.
12. Can download images from the internet for recovery.
13. Can remotely diagnose/repair relatives (privacy concerns noted).
14. Tailscale VPN configuration to avoid port forwarding/static IPs.
15. Hardware inside: Raspberry Pi 4 + specialized hat.
16. Three RJ45 jacks: Pi LAN + serial use + ATX adapter breakout.
17. Steel chassis may reduce Wi‑Fi signal strength.
18. ATX adapter provides power/reset and shows boot sequence in browser.
19. Possible mounting/flexibility for ATX adapter cable routing (3D printed bracket / PCI slot method).
20. Requires SD card flashing and network IP discovery if no OLED.
21. Web terminal commands used for admin password change.
22. Menu/UI compared to IPMI-style management.
23. Pricing: $160 hat-only, $250 full kit.
24. Commercial KVMs: $500–$1000 range.
25. Comparison: Tiny Pilot Voyager 2 at $360, polished package, claims better support.
26. Reviewer’s stance: Discord good for community but bad for searchability.
27. DIY option: can build using Raspberry Pi Zero 2 W around $50, but less polished and Pi availability is limited.
28. Reviewer concludes PiKVM is strong “middle ground.”

Speakers / perspectives (as presented)

• Main reviewer (primary): emphasizes real-world usability, latency expectations, performance limits (gaming), hardware integration (ATX, ports), and overall value vs commercial KVMs.
• Sponsor insertion (G.Skill): brief, unrelated to PiKVM performance details.
• PiKVM description (likely narrator/reviewer): explains architecture (Pi 4 + hat), setup steps (Pi Imager, IP discovery), and admin functions (web UI, passwords).
• Comparison viewpoint (reviewer): contrasts PiKVM with Tiny Pilot Voyager 2 and comments on support/community tradeoffs.
