GL.iNet has entered the low-cost KVM-over-IP market with the Comet (GL-RM1) remote KVM to remotely control any computer over an Ethernet connection with an HDMI port for video and audio input and a USB-C port for keyboard and mouse emulation.
It’s an alternative to the Sipeed NanoKVM (Cube) with a more powerful quad-core processor, 1GB RAM, an 8GB eMMc flash, a gigabit Ethernet port, and support for up to 2K (2160×1440) resolution at 60 FPS.
Comet GL-RM1 specifications:
- SoC – Quad-core CPU @ 1.5 GHz
- System Memory – 1GB DDR3
- Storage – 8GB eMMC flash
- Video & Audio Input – HDMI port up to 2K @ 60 FPS (2160 x 1440 @ 60 FPS); H.264 encodding with 30 to 60ms latency
- Networking – Gigabit Ethernet RJ45 port
- USB
- USB 2.0 Type-A port to connect peripherals like a Fingerbot or ATX power control board
- USB 2.0 Type-C port for mouse/keyboard emulation
- Misc – Reset button, dual color LED for power and device status
- Power Input – 5V/2A via USB Type-C port
- Power Consumption- About 3 Watts
- Dimensions – 80 x 60 x 17.5mm
- Weight – 85 grams
- Certifications – CE, WEEE, FCC, RoHS
The Comet (GL-RM1) device ships with an Ethernet cable, a USB cable, a warranty card, and a user manual. It runs a lightweight Linux OS and supports features such as remote KVM control, remote KVM viewing, virtual keyboard, clipboard, system function, hotkeys, image quality adjustment, screen rotation, file transfer, BIOS access, and power control.
The Comet works with the GLKVM program available for Windows and macOS, but we’re also told about “mobile/desktop application support” on the product page, so I assume Android and iOS apps are coming soon. More details about the cabling, wiring, and software can be found on the documentation website.
Pricing for the GL.iNet Comet (GL-RM1) KVM-over-IP solution is not quite as aggressive as for the Sipeed NanoKVM, but the specifications are better with higher resolution, and the jury is still out with regards to the security of the solution. The pre-order price is $69 with free shipping, and after the pre-order period, the price goes up to $89. You can also get a kit with an ATX Power control with a PCIe bracket for a total of $80.9 (pre-order) or $104.9 (MSRP).

Interesting. I’d have more faith in GL.iNet to write working software than in Sipeed, based on their respective track record in this domain, so this might end up as a better working solution for the short term. However, with NanoKVM being so cheap, there’s a chance that it will eventually work well over the long term if it continues to sell. One thing that is missing here and would be great would be a second HDMI connector to have a pass-through mode so that it doesn’t prevent from connecting a display. But this can be done externally using an Y-adapter with two outputs.
Jean-Luc,
Sipeed has finally opened the source of its device. See https://github.com/sipeed/NanoKVM/issues/1#issuecomment-2667345271
2560×1440 no? There’s no 2160×1440 resolution.
The datasheet says 2160 x 1440 @ 60FPS. They would also have likely claimed 2.5K if it was 2560×1440.
It’s not super common, but I can find some laptops and tablets with 2160 x 1440 resolution.
